THE PRESIDENT'S PAGE On my recent visit to the centre I was impressed by the National Parks, not only by the scenery and obvious good effects that Park management has had on tidiness and facilities but by the general geological accounts incorporated in park guides.

The N. T. Geological Surv ey have clearly done an excellent job in providing the park authorities with geological material .

From the questions we were asked by some other tourists there could well be an interest in some g eological details at specific sites, such as cross sections through gorges etc.

In our concern to gain public awareness of geology it would seem important for those in a position to do so to cooperate and where necessary to persuade Park managers to put more effort into e x plaining geological features.

In many parks, rocks are neglected compared with fauna and flora.

Perhaps the Society's Education Sub-Committees could assist here, especially by persuading local Colleges of Advanced Education to include more geology in Ecology and Resource Management courses .

The geological event of the decade, that will no · doubt have an impact on geological teaching even greater than the advent of Plate Tectonics, is the launching by the Academy of Science of ' Perspectives of the Earth'.

Some minor criticisms aside this is an excellently produced and spectacular book; the editors Ian Clarke and Barry Cook deserve our congratulations and the Academy's foresight and large financial commitment are praiseworthy .

I am told that the book is aimed at those students not intending to proceed to Tertiary studies in geology.

Nevertheless, it is certain to encourage many students to continue, and all first-year students would be well advised to read this book .

Personally I predict that its greatest sale potential will be as an introductory first-year text .

Many of us old timers will find much of instruction and inter e st in its pages too .

'Perspectives' is likely to force the restructuring of many Tertiary introductory courses or create difficulties where some large proportion of students may have already covered the basic first-year material; schools may also face difficulties in upgrading their courses to match the te x t-book.

Perhaps here also there may be a useful role for our State Education subcommittees to play in liaison between schools and tertiary institutions.

I have recentl y represented the Society on two National Committees - I.G . C.P. and N. C.S.E.S. Australian geologists have actively participated as Conveners and Correspondents in the UNESCO-sponsored old International Geological Correlation Program (now to be Cooperation Program) and there is a possibility that Mecke~ing (W . A. ) may be chosen as a special study site for intra - plate seismicity .

We congratulate Professor R. W. R. Rutland on his election as Chairman of the Scientific Committee and Professor J . Lovering on election as Board member of this large and important International undertaking.

The most important result of the Academy of Science National Committe e for Solid Earth Sciences meeting was the disbursement of Funds from the 25th I.G.C. Fund .

Since there were some $64 000 of requests for an available $15 000, there are bound to be some disappointments .

The Committee did its best to distribute the grants to promising y oung scientists spread evenly across the disciplines a n d geographically .

The G.S . A. received grants for the Tectonics Group meeting and the 7th A. G. C. (Cont i nue d p age 4 )

EDITORIAL

As this edition hits the newstands some geologists are gathering in Sydney to study one of the earth's and Australia's most precious resources - groundwater. A small but dedicated group of hydrogeologists in this country has worked in this field but it has not had the attention it deserves from the geological profession. Perhaps this international Conference will help to attract more recent graduates into a practical research field of great significance for Australia's future.

The much more newsworthy topic of the use and abuse of uranium has recently exercised the minds of geologists and engineers at a one-day symposium on safe disposal of radioThere is a wide divergence of opinion among active waste. the populace at large and among scientists on this topic and it is good to see geologists deeply involved in such socially significant matters.

An increased social awareness amongst geologists is clearly indicated in the programme for the forthcoming Seventh Convention (August 1984) where environment and resource management, and third world development are to be discussed in technical sessions, workshops and short courses.

Our increased involvement in such matters can only help the geological profession , giving it an 'improved image ' and possibly even more opportunities for a wider range of A wider base is essential if we are to lessen employment. the effects of the 'cyclic wave' pattern of employment which we suffer through our links with the basins and ranges of the mining stock market, a topic which has just been examined in detail by the Australian Institute of Geoscientists.

Australian geologists may be short of jobs at present but they are not short of words. An almost frightening array of meetings is scheduled: elastic tidal deposits , Canning Basin, fractures and ve ins, any old fossils, accretionary prisms, drainage basin erosion, higher e ducation, petroleum and minerals review, Landsat, structural deformation , feet (or metres) of clay, gran it oids and possib ly even humanoids all receive separate treatment, while the standard classics ANZAAS (Canberra May) Newcastle's Sydney Basin Confer ence (also May) provide solace for the weary in the month s leading to the Society's major meeting in August 1984.

Fortunately the mess of po tage is softened by exposure to real exposures - many of the meetings are based on field excursions and the evidence of the earth . Th is is as it should be . We cannot be a profession with its head in the clouds.

THE JOURNAL OF THE GEOLOGICAL SOCIETY OF AUSTRALIA IS CHANGING ITS NAME TO

Australian Journal of Earth Sciences EDITORIAL STATEMENT A new era is beginning in the life of the Society's Journal, as from the start of next year it will be published for the first time by Blackwell Scientific Publications i.e. publisher professional a (Australia). This organisation, which already publishes seven other scientific journals in Australia, will also promote and advertise our Journal world-wide. However, overall control will remain entirely with the Society. One major benefit of this new arrangement is that the workload of the Editor will be reduced as many of the time-consuming tasks such as layout and proof-reading, will be performed by Blackwell staff. This means that in the future the Editor will be able to concentrate more on scientific matters.

To promote a better international image , the Journal will be renamed the Australian J ournal of Earth Sciences and will have the new ISSN number 0812-0099 . Four issues will be published each year, but the existing volume numbering system will be continued, so that the four issues to appear in 1984 with the new title will be vol ume 31 .

Libraries are being advised of these changes. The cover of th e Journal will also b e redesigned and b e of slightly heavie r quality. The body of the Journal will be printed on a matt white paper, which is ideal for the high quality r ep roduction of photographs.

A n ew Notice to Contributors is b e ing produced along the lines of other Blackwell journals. The main differences with the ex isting procedur es are that all the Tables will again b e typ eset and that a preferred styl e of l ette ring and presentation of maps a nd diagrams, as indicated by mea ns of two examples, will be enc ouraged . The style of references will remain v irtually the same. Fold -out maps and diagrams a nd coloured photographs will continue to b e considered, if thought to b e scientifically necessary, but will be at some cost to the aut h or.

The number of free reprints has al so b een inc rease d to fifty.

There will b e no immediate major changes to the edito r ial policy a s the first issue is full from papers a lr eady submitted and accepted for publication. However , the long term aim is to try to widen th e sco pe of the Jo urnal and to make it somewhat less parochial . The l atter aspect, of course, is related to the old c hicken and egg problem. People tend to send their b est papers t o international journals as they feel that our Journa l is rather paroc hi al . Our Journal tends to b e rath e r parochial because people do not send their best papers to it! If we can b eak th is nexus we hav e th e potential for crea ting a n excellent journal wit h an international r ep u tation . Papers of the type we are seeking are ce rtai nl y b eing produced b y ma n y peopl e in Aus tra li a - wha t we have to do is to get mor e of them publish ed in the Aus tralia n Journal of Earth Scie nces . This co ul d be don e over th e n ext few years, for exampl e, if aut h ors considered sending even one or two of their papers to our Journal rath e r than to overseas journa l s .

This coupled with the sales drive of Blackw e ll co uld certai nl y c lw nge our imag e overseas .

This is not to say that the Journal will no l o nge r uc:ce pt locally orient e d papers. To the contr:iry - pa pe r s on loca l i ss u es mus t always have a place in our Journa l a nd 1. i.ll a l1.a ys b L' 1,P l co l'le as lon ;: as they are o f go od quality .

Speed of publication has always been a problem with most journals. One of the things we hope to achieve is the relatively fast publication of short papers. With four issues a year the only hold-up should be the refereeing time. In an attempt to reduce this for all papers the refereeing procedure is being streamlined by using the Editorial Board members as advisers in selecting the most suitable referees. Thereafter, the referees will communicate directly with the Editor rather than through the Editorial Board member. Then only in the case of conflicting referees reports would the Editorial Board member need to be consulted again.

EASTERN GOLDFIELDS GEOLOGICAL FIELD CONFERENCE (1983) A capacity audience of 175 crammed the Hob son Lecture Theatre of the Western Australian School of Mines to hear eight well presented papers from invited speakers at the inaugural Eastern Goldfields Geological Field Conference (1983). The highly successful venture was jointly sponsored by the Western Australian Division of the Geological Society of Australia and the Eastern Goldfields Geological Discussion Group, and comprised a one day symposium followed by two days examining key outcrops along two traverses through the greenstone successions in the Kalgoorlie-Kambalda area.

Account s of regional Archaean Geology were presented by Dennis Gee, Jack Hallberg and Tim Griffin. Dennis outlined the major features of greenstone distribution and evolution in the Yilgarn Block and highlighted the major problem of apparent overall synchroneity of greenstone belts and granites. Jack's paper described the geological evolution of the Leonora-Laverton area, and concluded with some comments on the importance of penetrating deformation associated with major linear tectonic zones in providing favourable sites for hydrothermal gold mineralization.

Tim and his co-authors questioned the two cycle models for greenstone evolution in the south Eastern Goldfields, and suggested that geological evidence could be interpreted in terms of a single cycle model.

David Groves outlined the metallogenic associations of Archaean greenstone terrains, and emphasised the importance of the contrasting platform-phase and rift-phase greenstone environments in controlling the nature and distribution of mineralization.

This paper, described by the author as "an unashamedl y arm-waving point of view", set the scene for more detailed accounts of mineralization in the Eastern Goldfields.

Neil Phillips emphasised the importance of iron-rich host rocks in locating hydrothermal gold deposits, Geoff Hopkin s gave a detailed review of the stratigraphy and structure of the Kal0oorlie Goldfield, and Phil Agnew described the mineralization and stratigraphy of the pro x imal volcanogenic massive sulphide deposit at Teutonic Bore.

Bryan Smith completed an excellent series of papers with a description of the geomorphical history of the Yilgarn Block and its significance to exploration.

The Organizing Committee of David Harley , Jeff Vaughan, Mike Donaldson, Tim Griffin and Peter Muhling, together with many other willing helpers, thoroughly earned the appreciation of all participants. Field excursions were ably led by Tim Griffin, Mike Hunter, Bill Keats and Dave Quick.

A 54-page volume, containing extended abstracts of papers and the detailed excursion guide, was edited by It is illustrated with a number of maps Peter Muhling. and diagrams, and the excursion-stops are sufficiently well-described and located to enable individuals to repeat the e xcursion using their own transport. The volume is available from Jeff Vaughan, W.A. School of Mine s, Ka lgoorlie at $10.00 per copy, but supplies are limited.

In closing the symposium, Russell Hud son commented on the quality of presentation of papers, the clear evidence of excellent collaboration between companies and research workers and the high level of enthusiasm and interest shown by the audience. The meeting noted with regret ti-1 at the Chairman of the W.A. Div isim,, Jim Ross, was unable to attend , and expressed their gratitude to him for initiating yet another successful GSA venture.

It is planned to hold further such conferences at These will Kalgoorlie and other regional centres. continue to provide both a stimulus and a suitable forum for geologists to present results of their projects and research work.

FIELDTRIPS FOR MEMBERS

or

LOOKING and LOVING at the LOOK DOWN

The 1982 survey of N.S.W. members conducted by the Education Sub-Committee showed that not only were many in favour of one-day excursions, but that there was also a great interest in weekend excursions.

In response to this, the first two-day excursion was organised during October by the Education Sub-Committee to Bungonia.

It was led by members Paul Carr and Brian Jones (Wollongong University) who have worked extensively in the area and used it as a venue for students' excursions.

At first it seemed somewhat surprising that so many would be interested in spending a weekend in the field when they no doubt spend a considerable amount of their working time doing just that.

It seemed even more surprising that Paul Carr, Brian Jones and Ruth Mawson (Macquarie University) would be willing to give up their free time to show fellow-members the area in which they work.

However, when it is considered that all members of the G.S.A. must have, at the very least, geology in common, and further that all must have done some training in geology, then the interest in the excursion shouldn't have come as such a surprise.

No doubt some also share a great interest in the work of others and to have the opportunity to spend a weekend in the field learning what their fellow-members are up to would be a further incentive, particularly at a time when most people are beginning to realise that not only is learning an ongoing process through life, but that it can also be quite pleasurable.

Once these aspects were given some thought, the actual organis tion of the excursion became less fraught with imagined problems.

However, although the common interest in geology could be seen as the key to success, a passage from an article "Mere hiccups in the history of time" written by Richard Fifield (New Scientist 9 June 1983, p. 704) gave rise to a further bout of gross apprehension.

The passage stated" .... The problem now for the scientists from each of the contributing areas (of geology) is how to make their work understandable and accessible to others. Attitudes, not just semantics, are involved because geolo~ists, like pet owners, tend to take on something of the character of their charges.

They vary from the hard core, to the volatile, the explosive, the fractious, to the intrusive.

All of them become territorial and when the boundaries are breached there can be some lively interchanges.

What is proof to the physicist may not be to the stratigrapher ... or the palaeontologist How can common ground be established?"

How can it indeed?

It is well known that "what's good for the academic need not be good for the man from industry".

The list of applicants did nothing to allay the new found fears.

Of the forty members who applied, 17% were school teachers, 33% were from the various universities and a staggering 49 % were from industry.

Further within these figures there was a huge range of individual interests.

How could the interest of such a diverse group be satisfied by a two-day fieldtrip? Would there be a breach of territorial boundaries.

Would the hard core control the intrusive, or would the whole weekend be explosive?

As it turn e d out the results should 9

Those who attended the e x cursion not only appeared to enjoy the geology that was offered, they also seemed to enjoy each other's company - thus dispelling the myth that the G.S . A. is rifted by the opposing forces of the academic geologists and those from industry.

PERSPICUOUS GEOLOGY? BOOK REVIEW

Geological Science: Perspectives of the Earth Edited I.F. Clark and B.J. Cook (xi, 650 pp) Australian Academy of Science, Canberra 1983 ($29.95 + freight)

The foreward to this weighty tome (1766 grms, even with flexible covers) tells us it is 'part of a set of teaching materials designed primarily for use with senior geology The title page courses in Australian schools in the 1980s.'

Student's tells us that 'integral with this v olume are: Manual--, Teacher's Guide - -.'

Perhaps it is a commentary on our education system, but a knowledge of the contents of these separate offerings is essential to a reasonable appraisal of this text book and This touches on the fundamental notion how it should be used. of what a text - book is all about - a matter to which I shall return later in this review. it is One's first impressions of the book are good; well set out and handsomely illustrated with many fine coloured photographs and diagrams, some black and white photographs, and numerous line drawings in brown and black .

While the last-named are clear, many are re - drawings with little imaginative modification from illustrations in ea rli er texts or references and one is tempted to play the game of 'spot the source'.

Part one The contents are divided into five main parts. looks at the earth from afar, beginning with the univer se and stars, the solar system, the moon, and the earth ' s envelopes of air and water, ending with the water which gets into the Part two considers the mater ia l s ground (99 pages in all). of the earth: minerals and crystals, igneous activity, sedimentary environments and the resulting rocks, and Part three examines fossils, metamorphism (145 pages).

Part four discusses relative and numerical time (93 pages). the earth's structur e and development (137 pages), and Part five deals with the applications of geology (138 pages) .

There is a useful glossary of terms and a twenty page appendix which describes and illustr ates what are somewhat Hands optimistically labelled common Australian fossils. up those who have recently found Glaessnerina, Wyndhamia, Pseudotcites or even your garden variety of Platypterygius?

11

The contents, size (650 pages) and arrangement of the book are, I believe, indications of the main problems which geological educators face in the high schools, and which have confronted the editors.

Firstly they have had the unenviable task of preparing a book which caters for the syllabi (take buses if you prefer) of all the various states. The bulk of readers may naively believe there is a corpus of geological knowledge which high school students might reasonably be expected to know.

Hands up again those who know what a Widmanstatten structure is, how to prepare stress trajectories, who can recite the series/ stages of the European and North American Ordovician, dunce's hats in the corner for those who don't know the Bouma sequence or where the Curnamona Craton is.

Perhaps some of the syllabi specify these matters - some of the authors clearly believe they are important, and the book is packed with such information.

I doubt if i t is really appropriate for the majority of H.S.C. geology students, who - according to the statistics are unlikely to study geology at the tertiary level, as the editors point out in their Teachers' Guide.

They also point out that 'the existence of this extensive set of materials must be treated with caution by teachers'.

While there are many good teachers of geology able to present this material effectively I am concerned that the many less-skilled teachers will see the text as a panacea for their deficiencies and will hand it over undiluted to their students.

This may well be disastrous both for the students and the cause of geological education.

It is inappropriate to dwell upon minor deficiencies and errors in the book - these are inevitable in a work of this size involving numerous authors.

For comment the time scale has suffered somewhat (end-papers and page 65), figure captions recommended for careful study are not always informative (e.g. page 46 encke's comet, page 192 karst topography, page 212 figure 9.23 paleocurrent map, page 230 figure 10.l0a cleavage) or suffer from the constraints of a rigid page layout.

What about lavger matters of concern? While satellite e x ploration is i mpo~tant and fascinating to many people I believe it is - peripheral to geology.

I would therefore argue it isn't where a geology text should begin. Likewise we shouldn't begin at the opposite end where matters minuter than microscopic require sophisticated equipment and a measure of belief remote from the human experience.

Wh y not star t at person-size scale, with the evidence of geolog y immed iatel y around us?

12

In this respect there are for me two notable deficiencies Firstly the attention given to landscape in the content. development is slight and not well-balanced , clearly the result of syllabus demands, together with abdication in this area in favour of the geographers - mare's the pity.

The second and more contentious is the almost completely exploitive attitudes expressed in the well-presented part five.

Geology and geologists have made many important contributions to the conservation movement in Australia (just look at some of the National Parks) and the Geological Society continues The reader of this text to be involved in such matters. would get no inkling (perhaps the inkliest) of these happenings.

I am sorry to find no discussion of what geological maps are all about. Granted there are numerous mapping problems in the Manuals, but some idea of the concepts inherent in geological mapping is very important and should feature in a text of this nature.

In consequence of such additions I would be happy to see reductions in the sections dealing with structural geology, palaeontology , mines and the market, and much of part one, I would also try to reduce the to name just a few matters. amount of terminology introduced.

The text, probably deliberately, is almost referenceless .

A major requirement in science is the personal checking of sources of information. The reader of this text would be hard put to check the material contained therein, or to pursue I believe this should be topics which might interest him. an important facet of science education, and should be a must for future offspring from this book, even though it hasn't been customary in many high school science books.

My verdicts - High School text? No , University text?

Maybe (some organizations already say yes) , reference and source book for secondary and tertiary teachers (and the brighter students)? Yes. I don't believe this book - the dedicated work of the last five years - gets to where it was intended . However it will have achieved its purpose as a landmark in geological education in Australia if it stimulates the Academy's Committ ee and the Geological Society's education sub-committee s to prepare a single syllabus for Australian schools (ranging possibly even from primary and junior high school to the H. S . C. level).

I believe the major cause of the weaknesses I discern in this book is the too large input by academics, who have quit e unreal levels of expectation about high school students a nd teaching.

13

The editors h a ve bravely faced the awesome geological monster, thus created, with the equanimity of Empedocles.

Unfortunately, I believe they have suffered the same fate.

If it is to be hoped that like Jules Verne's intrepid Professor Lidenbrock they will be brought unharmed out of the hollow earth where they can continue their herculean task of conquering Cerebrus - a creature with two terrifying heads, Academia and Syllabus.

Perhaps the second edition will solve not only the high school teachers' problems but the Lerna's also.

CRUSTASIAN STUDIES Dr. Ken McKenzie of Riverina College of Advanced Education recently made a working visit to the Peoples Republic of China under the terms of the Scientific Exchange Agreement between the Australian He spent about 3 weeks at Academy of Science and Academia Sinica. the Institute of Geology and Palaeontology of Nanjing, and a day at the Institute of Geological Sciences, Beijing.

Dr. McKenzie gave a series of lectures on Cretaceous-Recent Ostracoda (Crustacea) which were attended by workers from several petroleum and coal research institutes in China as well as by He also examined comparative material of ostracode specialists.

Cretaceous-Recent age from all over China (Yunnan, Tibet, Xinjiang, Guizhou, Jiangsu, Bohai)representing recently completed or current Palaeozoic and early research by the Nanjing Ostracoda group.

Mesozoic Ostracoda (Leperditicopida, Entomozoacea, Darwinulacea, 'Thuringia' facies) were examined at Nanjing; and TriassicCretaceous Darwinulacea, Cytheracea and Cypridacea of the Shanganxiang Basin, in the Collections at the Institute of Geological Sciences, Beijing.

The taxa reviewed briefly during his visit amounted to some 2000 species of Ostracoda and about 500 species of other Crustacea.

The highlight of his period at Nanjing was the opportunity to study for a whole day several beautifully preserved specimens of Kazacharthra (Triassic-Jurassic ) a crustacean group with affinities to Notostraca and endemic to western China and Siberia.

Important discussions were held with specialist colleagues at Nanjing on Cretaceous-Tertiar y correlations between China and also, on the proposal Australia and the other 'provinces' of Tethys; to publish (over 5 years) an 'Atlas of Indopacific Ostracoda' in which 1500-1750 ostracode species (mainly Cretaceous-Cainozo ic) would be described and figured.

The opportunity was taken to visit Beijing University and to have some ancillary discussions with representatives of the South China Agricultural College.

It is hoped there will be visits by Chinese Ostracoda (!) and other crustacean specialists to Australia in 1984/85; and a Chinese delegation to the 'Shallow Tethys 2' conference being organised at Riverina C.A.E. for 1986.

Ken McKenzie writes: My working visit to the Peoples Republic of China was certainly Although I had not exvery worthwhile in a professional sense. pected to do so much lecturing, the need to prepare a set of lectures helped organise my thinking in several areas of current I saw an incredible amount of material - several times research. more in the one month than I have ever had to cope with in a normal This immediate experience is more enduring and exact than year.

It was also clear that my visit was a professionally positive Mainly experience for Chinese colleagues especially at Nanjing. this was due to the fact that their background and training is almost exclusively palaeontologic, taxonomic and biostratigraphic whereas mine includes about a quarter century of experience with the ecology of living faunas (marine, estuarine, continental), plus expertise in dissection techniques and in functional interpretation A stemming from my years at the British Museum (Natural History). common factor was our mutual interest in petroleum exploration which I provides a powerful economic incentive for ostracode research. was able to indicate several avenues for more detailed environmental includinterpretation based on features of the ostracode carapace: ing shape, sex dimorphism, muscle scars, ornamentation.

The need/demand for ostracode studies in China has been matched by a growth in the Ostracoda group at Nanjing from one (Prof. Hou) in the early S0's to the present dozen workers, including a doctoral If the whole of China is considered, this growth research student. is far greater since I was assured that there are now about 100 ostracode specialists.

This explosive growth is matched in other areas of palaeontology.

Before 1949 there were fewer than 30 palaeontologists in China (they included Profs. Mu and Chang of the Nanjing Institute) now the number is well over 1000 (Geol. Soc. America Spee. Pap. 187, publ. · 1981).

Australian palaeontology certainly deserves a phase of such growth in order to serve the exploration industry more effectively.

The richness of the palaeontological materials available in I was assured that when I next revisited China is truly impressive. the Institute at Nanjing they would have as much new material to show Much of this material is collected by field me as on this visit. geologists, for example, all Assoc. Prof. Chen's material of Clearly, such field Kazacharthra was collected by a field party. geologists are well trained.

My hosts regularly invited my critical comments and suggestions for improvement in their training, procedures and facilities.

I was very impressed by the good state of the type collections at Nanjing; and also by the fact that every specimen I examined carried a museum or field number. ii) On the other hand, exhibits at the small museum in the Nanjing Institute were not well displayed and there is room for improvement in this field. iii) The preparation laboratories were well set up and efficient.

I was impressed by the technique for treating limestone (outlined earlier) and gave Prof. Hou an outline of my own technique (sodium hexametaphosphate plus sodium bicarbonate) for breaking down marls which apparently give their prepators some Dr. Wang's dielectric separation method (Beijing) problems.

At was excellent for mudstones and transitional facies.

Beijing, too, some other technique, such as mine, would be required for marls. iv) Chinese palaeontologists specialising in Crustacea generally lack expertise with living faunas and would profit by i)

opportunities to acquire this expertise through further training.

It can be applied in more detailed palaeoenvironmental interpretations for which there is a solid economic incentive in China's coal and petroleum industry (Ostracoda, Chonchostraca); also in its phospherite exploration program (Bradoriida) .

Both the Vice-Director at the Institute of Geology and Palaeontology, Nanjing, Prof. Mu Enzhi, and the President of the Institute of Geology, Beijing, Prof. Shen Qiren, conveyed through me their good wishes to all Australian colleagues, in particular those who have visited the Peoples Republic of China under the aegis of the Scientific Exchange Agreement.

HAVE A BALL AT THE FOSSIL HAUL

At midnight in the museum hall the fossils gathered for a ball Amidst the mastodonic wassail I caught the eye of one small fossil 'Cheer up, sad world', he said, and winked ...

It's kind of fun to be extinct'.

So begins and ends Ogden Nash's verse for Saint-Saens 'Carnival of the Animals'.

Now it seems that you can really catch the eye, ear and tooth of many thousands of fossils at Stuart Baldwin's Fossil Hall in Essex, U.K. Many of Baldwin's original specimens have been used in the fossil wall constructed at the Geological Museum London.

These are part of a collection of more than 100,000 specimens he gathered as an amateur.

Since 1971 he has been making high class reproductions in his spare time but in 1981 became full time, and now, in his own words is 'a happy man, working full-time at my hobby fossils'.

Wall charts, crystal and rock specimens, are also sold as well as geological (mainly palaeontology) books - which he is also interested in purchasing.

Recent series of interest are Trace Fossils and Precambrian Body Fossils. Now you can teach yourself Palaeontology! For further details write to S.A. Baldwin, Fossil Hall, Boars Tye Road, Silver End, Witham, Essex, CMS, 3QA, U.K.

PERISH THE EDITOR - IT'S PUBLISHED! Ross Staines tells me that I have got out of step with stratigraphic matters by publishing the 'reserved' category names in Deletions List No. 9 (August 1983), so they are thus not deletions.

It's people like me who give stratigraphic nomenclature a bad name!

To atone I publish herewith List No. 10, which I am reliably informed has been suitably adjusted so that the names are not therefore published.

LIST NO. 10 DELETIONS FROM RESERVED NAMES INDEX OF NAMES RECORDED FOR MORE THAN FIVE YEARS At the meeting of the Stratigraphic Nomenclature Committee held in August 1973, it was decided that reserved names held for 5 years and not yet published should be removed from the index of reserved names, thereby freeing them for other enquirers, unless the original reserver indicates that he still intends to use the name.

The list is A list of names held for 5 years or more follows. being sent to those organisations which receive the Bi-monthly Variations List and not to authors.

Authors who would like names to remain in the reserved names index should write before 31 December 1983 to the Officer-in-Charge, The Central Register of Australian Stratigraphic Names, Bureau of Mineral Resources Geology and Geophysics, GPO Box 378, Canberra, ACT 2601.

It is possible that some of the names have been published but The not indexed in the Central Register of Stratigraphic Names.

Officer-in-Charge would appreciate advice on where any such published names can be found.

LAVA COME BACK TO ME MODERN AND ANCIENT VOLCANIC SUCCESSIONS - AN APPROACH TO ANALYSIS OF FACIES, ENVIRONMENTS OF DEPOSITION, AND TECTONIC SETTING. (EAST GIPPSLAND, MAY 30th - JUNE 3rd 1983) This is the second year that this highly commendable course has been run by the Department of Earth Sciences, Monash University, and judging by the wide response from geologists, this course is filling The course organisers were R.A.F. Cas and an important need.

The J.V. Wright, the latter now with British Petroleum, London. venue was picturesque Paynesville, eastern Victoria.

The introductory description of the course provided by the organisers states that it is "an intensive course of lectures, practicals and field classes ... (whose) key aim is to provide participants with an approach for the analysis of ancient volcanic successions, Coverage will be comprehensive facies types, and lateral variations. to encompass everything from terminology and identification of rock types to a discussion of some of the most recent advances in pyroclastic geology".

The course ran for five days and was broken into three days of lectures and laboratory work and two full day field trips to the Buchan-Murrin dal region, where special emphasis was given to the Participants volcanic setting of the Snowy River Volcanics. numbered 38 and comprised 23 company representative s, 3 government employees, and 12 from academic institutions.

Much of the laboratory and lecture work revolved around an excellent book of course notes prepared by Ray Cas and John Wright.

All told, the volume comprises 12 chapters (320 pages), with each chapter grouped into notes, references and diagrams. Examples of 1. Some properties of magmas relevant to the chapter headings are: 3. Modern pyroclastic deposits; their physical behaviour; 8. Crystal 5. Classification of pyroclastic and volcanic rocks; The overall 11. Analysis of ancient volcanic successions. tuffs; format of the notes is not unlike the well known "Petrology of Sedimentary Rocks" by R. L. Folk, but is more comprehensive and contains extensive references.

The major thrust of the entire week was to relate tephra studies in young active terrains with older examples in Eastern Australia.

Consequently John Wright tended to concentrate on more recent examples with emphasis on his own work and others, in areas such as the Central Rio Caliente, Mexico; Pantelleria, Italy; Puerto Rico; In contrast Ray Cas and SW U.S.A. Volcanic region, New Zealand; demonstrated how advances in these recent examples could be applied in older volcanic settings and examples ranged from the Tertiary basalts of Western Victoria, to the Devonian Merrions Tuff, N.S.W. and the Snowy River Volcanics, Victoria.

Field trips were well organised and each participant was given a guide book containing maps, and explanation of regional geology, Of particular interest and field sketches of the various outcrops. was the second field trip to the Murrindal River which contained a very informative section through a Devonian caldera complex containing rhyolite bodies, an acid tuff ring, ignimbrites, and epiclastic

A departure from the first course was a brief discussion sediments. on ore deposits and volcanism given by I. Plimer .

It is our belief that this course is of particular significanc e to the understandi ng of volcanic successions in Australia and its justificatio n will be witnessed over the next few years, with a renewed interest in, and better understandi ng of volcanic facies, modes of pyroclastic emplacemen t, and the relationshi p between pyroOf significanc e was the wide clastic and epiclastic deposits. industry support and all were unanimous that they would be recommending to the various companies that other staff members be sent should the course be held again.

Victorian Geology The ses This new publication from the Department of Geology at the University of Melbourne compiled by John Webb shows the wide range of topics and areas which has been studied by senior and post-gradua te students in Melbourne's institution s of higher learning since 1931.

Although only the thesis titles are given, two location maps show thesis areas in Victoria which have been mapped in some detail.

Numerous now-famous names, which will not be mentioned, adorn the pages of this compendium. An interesting and perhaps significant feature of the records is that while all Ph.D. theses remain intact within various hallowed walls, one M.Sc. thesis is missing and five and three half Honours theses have vanished.

Those wishing to pursue these statistical matters further, should apply post-haste for the copies ($10 including postage) to the Administra tive Assistant, Department of Geology, University of Me lbourne, Parkville, Victoria 3052.

There is probably still valuable unpublished material waiting to be pirated or spirited away from these dusty tomes.

Book Review GEOCHEMICAL EXPLORATION IN DEEPLY WEATHERED TERRAIN Edited by Raymond E. Smith, CSIRO Institute of Energy and Earth Resources, Division of Mineralogy, Floreat Park, Western Australia, 1982. 190 pages.

The volume contains discussion papers that formed the core of a number of CSIRO workshops (held in Perth and Sydney) with the The contributions are entirely from 14 CSIRO scientists same title. from the Division of Mineralogy (12) and the Division of Mathematics The authorship of the papers is a bewildering and Statistics (2). variety of combinations and permutations of the authors: R.E. Smith alone, and in combination with others, is responsible for 53 pages; major contributions (20 pages or more) are made in various combinations of C.R.M. Butt, G.F. Taylor, M.R. Thornber, A.W. Mann, and other contributors are J.A. Hallberg, E.H. Nickel, J.R. Wilmshurst; J.L. Perdrix, G.R. Carr, B.L. Gulson and M. Vaasjoki.

After a very brief introduction (section 1), two longer introductory sections - "Beneath the Weathered Layer (Section 2) and "Weathering and the Australian Landscape" (Section 3) - provide background information on element associations in mineral deposits and host rocks, on the weathering history of Australia and on some ideas on identifying deeply weathered rocks, and sampling and analysis.

A major section of "Weathering of Sulphide Bodies" (Section 4) is The chemical processes of gossan formation and devoted to gossans. mineralogical and textural features are described as a prelude to papers on assessment and classification and an account of geochemical identification of gossans related to mineralization in Western Australia and Queensland.

Section 5 ("Geochemical Dispersion") is concerned with theoretIncluded ical and practical consideration of element dispersion. are discussions of the effect of pH and Eh on the solubility of Cu, Pb, Zn, and U, and the mobility of Au and Ag in lateritic weathering General models for geochemical halos in weathered bedprofiles. rock and in transported overburden are presented; a brief account of the application of some of the principles is given for the Redross, Elura, Dapville, and Golden Grove deposits.

The topic of "Data Treatment" is given only 4 pages in Section 6.

The volume concludes with Section 7 on "Specific Exploration Techniques" which discusses Pb isotopes, Hg, He, and the use of a portReferences for all the able digital voltarnrneter for heavy metals. papers are collected at the end of the volume.

I have found this a difficult volume to review intelligently Much of the material included has already been puband fairly. lished in various forms over the past 5 years, or is about to be published. Nevertheless, it is a useful compilation that brings together in summary form a wide range of experience with exploration geochemistry under the peculiarly difficult Australian conditions.

Insofar as the great bulk of exploration geochemistry research in Australia which is published is conducted by CSIRO, this is close to a 'state-of-the-art' account. The editor might consider gathering other information from Non-CSIRO sources - especially on data treatment - to compile an expanded version.

It has been felt that highly technical dissertations would not One be appropriate and thus a broad brush approach was adopted. volume covering such a vast and complex canvas could do no more.

In effect preliminary outlines have been the goal with full knowledge that as progress is made with any specific study, recourse will have to be had to counsel and literature of a much higher level of detail.

More than a little consideration had to be given to the question It was recognized that the main of who could utilize the book. thrust should be towards: - policy makers of developing countries who only occassionally are geoscientists .

- geologists and mining engineers (often graduates of undernourished universities in the developing world) who have had little opportunity to grow professionally through participation in well planned, executed and sustained field work and mineral development programmes teachers and students looking for an overview relating the technical and other aspects of mineral resources development policies.

AGID is concerned about the better development of mineral resources and believes that geoscientists can play an important role in policy making, over and above their purely technical assignments.

There is also a need for non-geoscien tists to better understand the complexities of the technical problems and the general framework within which all types of mineral resources must be e x plored, develThis volume is therefore oped and exploited, at the whatever scale. another AGID contribution to the on-going discussion and supplements earlier publications on mineral resources.

BJ Min Sci Tech Offic. Comm HIAF IEER CSIRO Nth. Ryde Lab. Those in the know will understand that the above tells us Barry Jones introduced 'a new dimension of high technology to the minerals energy, and geologically related industries' by officially commissioning CSIRO's Heavy Ion Analytical Facility which produces high energy particles in a narrow beam to provide a rapid but highly accurate analysis of any target material!

Apart from use by the Di v ision of Mineral Physics it is expected that the accelerator will 'generate and sustain collaborative research with other CSIRO Divisions and groups in industry, universities and other research institutions'.

ISOCHRONIC Attributed to R Miller, formerly a PhD student at the University of Alberta.

Although it yields the date you lacked (Or any other date in fa c t), Don't ever base a paper on The single-datum monochron. ( some wag has added

'' or moronchron

The duochron is perfect for The dumb, the novice and the raw, Because the utterly inept Can find the slope and intercept.

The scatterchron or errorchron Describes a sort of polygon.

Just choose an age, _ and fudge a bit, And somewhere there · s a perfect fit.

. ... .,,.

The isochron is rather rare, But if you pick your points with care, Rejecting those which don't fall on The line, behold! An isochron!
