It is pleasing to note the award of the 1983 ANZMS medal to Professor Dorothy Hill and the election to the Academy of Science of one of her old students, Professor K.S.W. Campbell. W.E. (Bill) Foskett has retired after many years as Administrative Officer. I thank him for his service and wish him well in the future; David Probert (N.S.W. Geol. Surv.) has agreed to take over the position.

Geological historians and geophysicists are currently setting up Specialist Groups and if they are as successful as our other Specialist Groups their activities will greatly enhance the Society. Committees are actively working on three major symposia; February 1984 Structures, Bermagui (SGTSG), August 1984 7th GSA Convention Sydney (N . S.W. Divis.), 1986 12th International Sedimentological Congress, Canberra (SGS). The Victorian Division rep orts a highly successful Broken Hill Excursion. Divisional Monuments committees are actively working on the designation and description of National Heritage sites. The point of these comments is to indicate that the Society is alive and working well. Much has been written recently about poor public relations in geology, it is up to us to inform our local communities, other scie~tists and even other non-member geologists about our work and achievements.

Following Rudi Brunnschweiler's letter (AG43), Executive hopes to launch a membership drive shortly - see advertisement for poster competition this issue.

Also, in response no doubt to Vince Morand's letter (AG44), The 7th CSA Convention Committee is seeking ways to reduce the cost of excursions for students. The Australian Geologist is your newsletter - if you have a gripe or some interesting information send it to the Editor.

In the recent postal ballot, Council voted 100% in favour of accepting Blackwell's offer to publish our Journal; there was also a majority in favour of changing the name to 'Australian Journal of Earth Sciences' with some indication that the Journal belongs to the GSA. Executive delayed implementing this decision because we received concurrently a proposal from the Director of the BMR to consider a joint publication venture. After numerous discussions and negotiations and considerable effort, on the part of Sandy Renwick in particular, for which we are most grateful, it ·appears that a merger of the BMR and GSA Journals is not feasible at this time.

Executive has now decided to sign a contract with Blackwell Scientific Publishers (Australia) Pty. Ltd. to publish an Australian Journal of Earth Sciences on our behalf. Executive is also pleased to appoint Dr. Roger Le Maitre of Melbourne University as Honorary Editor of the new Journal. A draft statement of Editorial Policy will be included in the next Australian Geologist .

The Society owes a considerable debt to Assoc. Professor Ron Vernon for continuing to act as Editor after his retirement (as Editor) and thereby ensuring a smooth change over.

The Australian Geologist

1st August, 1983

Newsletter No. 45

EDITORIAL OUR PAST IS CATCHING UP Elsewhere in this issue Barry Cooper reports on the response he has received to forming a Geoscience History Group within the Society. A wide variety of interests has already been indicated from the 23 members who have responded so far and Barry believes he has only 'touched the tip of the iceberg'.

It is to be hoped that more people will surface and allow a better isostatic balance between the affairs of the present (and future) within the Society and some thoughtful study of how we have reached our present situation in geology, specially in Australia.

Two book reviews in this newsletter and others in recent issues point to the growing interest in studying our origins, and it is to be hoped that formal establishment will be possible in August, 1984 followed shortly after by the first of regular sessions at Geological Conventions.

The Society was represented in August, 1982 at the History of Australian Science workshop at Academy of Science, Canberra and it is pleasing to see that the Academy's Council will be sponsoring a bicentennial volume on the History of Australian Science.

The theme of the volume will be 'man's attempt to understand nature in an Australian environment', a theme ready-made for geological topics.

Editorship is in the very capable hands of Professor Rod Home, History and Philosophy of Science Department, University of Melbourne, who is also editing a newsletter of the project, No. l having appeared in May. Historically-m inded buffs should get their hands on a copy of this newsletter and consider whether they can't make a useful contribution about the past for the future.

WANTED DEAD OR ALIVE* MEMBERS $100 Reward (*Preferably alive) For t he best designed poster (50 x 70 cm max size) to hang up wherever geologists hang out to persuade those not already members to join the G.S.A ..

Letter to the Editor Sir : Dr . Alec Trendall , in a Letter to the Editor (The Australian Geologist 25 . 3 . 1983) , discussed the subdivis i on and nomenclature of Precambrian time and rocks .

His letter no doubt was written with tongue in cheek .

A few points need clarification .

The Subcommission on Precambrian Stratigraphy of the International Union of Geological Sciences (not International Subcommission on Precambrian Stratigraphy) was established in 1966 and has met several times in various parts of the world .

One of its meetings was held in Adelaide in 1973, the last meeting was at Tanta, Egypt, early in November, 1982 , and the next meeting, to be organized by Ken Plumb, Chairman Elect of the Subcommission, will be in Australia in 1986 or 1987 .

It seems to be generally believed that the boundaries suggested by the Subcommission are legislatively decreed .

This is far from the truth.

The proposals of all the Subcommissions of the Commission on Stratigraphy of the IUGS are only suggestions .

You can take them or leave them .

One man's food is another's poison .

I might add that the boundaries suggested by the Subcommission on Precambrian Stratigraphy are based on serious research carried out

by Members and Correspondents of the Subcommission .

If Australia wants to reach a national solution, the Subcommission, as a body, most certainly will not interfere .

It will continue its work towards establishing an acceptable stratigraphic subdivision of the Precambrian, however , without the help of sweepstakes and lotteries .

Kal Rankama Helsinki and Sydney -1983 • Prider Lecture Dr . Russell Hudson (Division .of Mineralogy , CSIRO) delivered the inaugural Prider Lecture to 550 senior high school students on Tuesday, 18th April .

The students, who came from 35 metropolitan high schools, heard Dr . Hudson talk on the topic "Chemical and Physical Controls of Ore Formation" .

After outlining the importance of mining to the Western Australian economy , Dr . Hudson explained the concept of an ore and discussed levels of element concentration which are necessary to bring element crustal abundances up to concentrations which can be e xploited economically.

Concentration of elements b y igneous processes , through liquid immiscibility , crystal fractionation and enrichment in end-stage fluids were described by means of diagrams, demonstrations and colour slides of ore deposits .

Dr . Hudson then considered h y drothermal concentration of elements and those processes which operate at the surface of the Earth.

His demonstration of the physical concentration of gold will be remembered especially by the students who participated in a gold panning competition .

By the end of an informative and entertaining address , Dr . Hudson's audience had added considerably to their knowledge o~ Western Australian ore deposits as well as gaining a n understanding of t~e processes involved in their formation .

Topics which he link ed closely with school chemistry theory included element partitioning (crystal-liquid , liquid-liquid) , iron transport and deposition , concentration of baux ite and the transport/deposition of gold .

Students saw the scope of chemistry in geology.

The success o f the inaugural Prider Lecture was evident from the attentive aud ien ce and its warm acclamation .

Plann ing for the 1984 Prider Lecture is underwa y.

STATUS QUO VADIS - AGC Reports

•

~.

The Australian Geoscience Council has produced its H a n d ~ , first Annual Report containing, as the cover tells us, articles on 'issues of current interest and concern to Australia's Geoscientific Community'.

This is certainly true.

'The Status of the Geosciences in Australia' is a 16 page summary of significant events in 22 designated fields of endeavour, from Antarctic studies to structural geology and tectonics which it is intended will be updated annually. The only material which isn't enlightening is the coverage of 1:1,000,000 geological and geophysical mapping which has been achieved (or not?) according to the maps of Australia reproduced and some addition to the legend is recommended in future reports.

The shorter article 'Trends in Government and Industry sponsored Geoscience Research in Australia' makes several disturbing points one that in the past eight years expenditure has fallen about 40% in real terms and is now only about 0.04% of GDP, second t~at there is no increase in total research output (man-years) from 1978/79, following a marked decline through the 70s.

It is interesting that Vertebrate Palaeontology research is being carried on in at least a third of the 44 (of 56) organisations which supplied information, while only 20% are involved in geomorphology research.

Through the generosity of various companies (mostly mining) a survey on 'Geoscientists in Australia' has been funded and is being carried out by Dr Morgan Sant (University of NSW). The preliminary results are outlined in a brief text and numerous tables.

You will all doubtless be relieved to know there is no such person as a typical geoscientist. Sant points out that based on the opinion of employers 'it is clear that certain basic skills need to be given a very hard look (at) by educationists~ Respondents were noticeably coy about identifying teaching institutions ~eemed to give good training', some employers declined to answer at all, and some were outspokenly critical of all Australian geoscience education'.

However, all is not lost and some institutions get a mention.

A compilation of considerable interest is the statement of noteworthy mineral, coal and petroleum discoveries 1977-82. While evaluation is still proceeding on many of the sites, it is clear that geology is contributing to the future development of our non-renewable resources. One interesting feature is the lack of any new black coal deposits, whereas brown coal in various forms is turning up in abundance.

Data on the member Societies of the Council, its constitution and By-laws supplement the reports of the Council's first officers, President Bruce Webb, Secretary Colin Branch and Treasurer Pat Walker.

The report is published through a generous grant from C.S.I.R.O. (Divisions of Mineralogy and Mineral Physics).

All in all it is a very satisfactory beginning for a body which shows promise of making a major contribution on behalf of the geological sciences to the development of Australia, 'by providing advice ..... without political, social or industrial bias'.

The President for 1983-84 is Gerry Govett (University of NSW) and Secretary John Gilfillan PO Box 422 Lane Cove NSW 2006. Phone (02) 436 1056.

This is an Annual Report which should be made known to the widest circle possible, inside and outside the profession.

Radioactive Waste Management : A Geoscientific Assessment A s ymposium is being jointly sponsored by the Australian Geoscience Council and the Australian Academy of Science . The symposium is scheduled to be held in ·the Australian Academy of Sc i ence , Canberra on Wednesday , 30 November 1983.

The symposium has been set up as an apolitical assessment by geoscientists of the methods and controls for the land-based storage of high- and low-level radioactive wastes from the nuclear power industry . The sponsoring bodies are very sensitive to the strong emotions aroused by any discussion of radioactive waste management but they believe that the community is entitled to hear what Australian geoscientists active in the area have to contribute to the debate .

It is crucial for the success of the symposium that all groups interested in a geoscientific assessment of the problems should participate in the programme and particularly in the discussion groups which will follow the formal presentations .

BUNGONIA IS GORGEOUS The N.S.W. Division' s enthusias tic Education sub-comm ittee is holding its second excursion of 1983 to the Bungonia area SaturdaySunday, October 15-16, with overnight accommod ation for 50 at the Field Centre . Leaders are Paul Carr and Brian Jones, assisted by Ruth Mawson and Armstrong Osborne. Contact Robyn Stutchbur y, Geology and Mining Museum, 36 George Street, Sydney (02) 241 3662 or (02) 241 3774 for bookings.

Paul Carr outlines some of the delights in store in the following .

The oldest rocks in the Marulan - Windellam a region are the Late Ordovicia n Tallong Beds. These consist of tightly to isoclinic ally folded, micaceous fine-grain ed quartz-ri ch sandstone with shale, slate, siltstone , phyllite and chert interbeds . The dark, carbonace ous slate contains numerous graptolit es of Late Ordovicia n age and sandy units exhibit Bouma sequences and a variety of sedimenta ry structure s characte ristic of depositio n from turbidity currents.

The Tallong Beds are unconform ably overlain by, or are in fault contact with, the shallow marine Late Silurian to Early Devonian Bungonia Limestone which has been subdivide d into five informal units (lower limestone , lower shale, middle limestone , upper shale and upper limestone ) in the Bungonia area. Late Silurian (Ludlovian ) fossils occur in the lower three units whereas an Early Devonian (Lochkovia n) fauna has been recorded from the upper shale. The Bungonia Limestone only extends from Marulan South to Inverary, although a laterally equivalen t Late Silurian limestone is conformab ly overlain by a thick sequence of tuffaceou s sandstone , tuff and dacite named the Tangerang Formation .

The Early Devonian Tangerang Formation forms the basal unit of the Bindook Volcanic Complex in the Marulan - Windellam a area.

It consists of an interbedd ed sequence of shallow marine limestone , shale, conglome rate, terrigeno us and volcanicl astic arenite, tuff and dacitic lava flows. Age diagnosti c (Lochkovia n) faunas within the lower part of the Tangerang Formation suggest a lateral interdigi tation with the upper part of the Bungonia Limestone . Three distinctiv e members have been recognize d within the Tangerang Formation , namely the Carne Dacite Member, the Windellam a Limestone Member and the Aloes Tuff. Ashflow, ashfall, lenticula r pumiceous and accretion ary lapilli tuff, as well as volcanic breccia and agglomera te, are all represent ed within the formation .

The Marulan Batholith is a composite body which has intrusive contacts with the Ordovicia n to Early Devonian sedimenta ry and volcanic rocks and is non-confo rmably overlain in part by Late Devonian strata and rocks of the Sydney Basin. Skarns have been produced at some contacts between plutons of the batholith and limestone s of the Bungonia Limestone whereas tourmalin e-quartz rocks are developed along some contacts with the Tangerang Formation .

Plutons have I-type characte ristics and range from basic to acidic types.

Detailed field, petrograp hic and chemical studies indicate that the rocks on the batholith are closely associate d in time, space, petrograp hy and geochemis try with the volcanic rocks of the Tangerang Formation .

Points of interest include: Spectacul ar scenery - Tallong Beds - Bungonia Limestone - Tangerang Formation - Marulan Batholith geopetal structure s - various fossils - angular unconform ity Bouma sequences - various sedimenta ry structure s - accretion ary lapilli - tourmalin e-quartz rocks - skarns - if we have acc e ss to the Limestone Quarry.

YEA, THOUGH THE GHOST AND GOOL CRACK HARDY THEY MUST GO Sir: The role of the Stratigraphic Nomenclature Committee of the Geological Society of Australia is to encourage the orderly use of stratigraphic names in Australia and its Territories.

The Stratigraphic Index area of the Bureau of Mineral Resources provides the necessary support for this task by maintaining a Register of Stratigraphic Names.

One of the duties of the Registry staff is to keep geoscientists informed of the new names that are being recorded in the Register as reserved, published or deleted.

This task is carried out by the circulation of a Variation List every two months and a Deletions List every year to 8 State sub-committee conveners, 13 State Surveys, 32 tertiary institutions and 23 companies.

Although the Lists appear to have a wide circulation, we have found that many individuals do not see them, more importantly the Deletions List.

The Deletions List notifies stratigraphic names which have been reserved for more than five years.

Unless we are advised that reservation for a further period is sought, these names are deleted from the Register and thus become available for use by other workers.

To ensure that many more authors see a copy of this list we would like to use the pages of "The Australian Geologist" to supplement our normal distribution method.

A copy of the 1982 list is shown on pages The following table shows the number of deletions in the past nine lists.

Deletion List Number

The next Deletions List is due in July 1983 and we expect it to contain around 110 names.

LIST NO. 9 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.

Proposed Geoscience History Specialist Group The response to the proposal in the March 1983 'Australian Geologist' suggests that there are sufficient members interested in forming this group.

23 members have indicated an interest up till the end of June, but my impression is that we, have only touched 'the tip of the iceberg'. Many members probably fear to commit themselves in case they are burdened with new obligations and responsibilities.

Such fears are certainly unfounded.

Respondents so far have indicated an interest in the following topics:The history and philosophy of the mining and petroleum industries, government geoscience services together with geoscience teaching institutions.

Biographical studies of prominent geoscientists.

The hi$torical change and progressive development of specific disciplines within the geosciences e.g. geophysics, geomorphology, palaeontology, tectonics.

How geological thinking evolved distinctively in Australia when placed in a world context.

The history and progress of geologic understanding of specific regions in Australia.

The appreciation of old and rare books and illustrations dealing with the geosciences.

Oral history ~nd reminiscences of senior and retired geologists.

Preservation of the cultural heritage associated with the geosciences. i.e.

old mining areas, gravestones, classic geological sites, written records.

Historical development and use of building stones in Australia.

Production of bibliographies dealing with the above topics.

With interests embracing such a wide variety of topics a Geoscience History Group may be interdisciplinary with almost any other branch of geology and certain can make an important contribution to each specialisation. Obviously, the way we study and have studied geology is critical to our present approach to a problem.

If you are interested in belonging to the Geoscience History Group please contact Dr. B.J. Cooper, S.A. Department of Mines and Energy, P.O. Box 151, Eastwood, S.A., 5063.

BOOK REVIEW Geology of N. S . W. South Coast by C . McA. Powell . S . G. T . S . G. Field Guide No . 1 , $10 . 00 . Geo l. Soc . Aust . Inc . Sydn e y.

If you are planning to get away from it a ll on a far south coast holiday don ' t take this book , for it will p l unge you i n to a web of Mystery (Bay) and end y ou up at the distal end of the nearest Ordovician outer - arc slope or some other exotic terrain .

You will be beset with poly modal palaeocurrent patterns , arkosic-volcolithic conglomerate-sandstone-mudstone facies , helicitic crenulation cleavage , egg-carton interference folds , conjugate box - folds , en- echelon vein array s, vergence of S½ with respect to So, and Bo\lffia C(D)E . I hope I make myself abysally plain .

This is not a book for him (or her , ) who yearns for a simple sandstone or syncline, he or she must be content with quartzose litharenites, parasitic F2 folds on major F2 antiforrns , and other detailed evidence which Chris Powell and his six contributors has amassed in attempting to elucidate the Palaeo z oic history of this portion of the Lachlan Fold Belt .

This closely packed document of 120 pages is intended to be a book for the specialist interested in e x amining the field evidence . This is presented in a series of detailed plans and sections along the coast from Mallacoota to Batemans Bay accompanied b y discussion , arranged in the form of a self-guiding 5 day e x cursion .

The e xcursion details are preceded by a discussion of the structural and geological history of the area accompanied by regional maps and block diagrams , all of which are clear , apart from some overprinting (e.g . Figure 34) , and erosion of the stippling on parts of Figures 1 and 5 .

The book is packed with information and even if you aren ' t a fanatical structural fiend you will gain much benefit by taking it when you ne x t visit the Potato Point profile ~r your favourite fishing spot, when it is likely to fill you with humility at all the evidence that has been looking you in the eye but which you never did see nor understand .

There is a great amount of information in this book , much of it formerl y unpublished . The authors and the sponsoring Specialist Group in Tectonics and Structural Geology are to be congratulated on the production of what promises to be the first of an e x cellent series .

Is the Tantawangalo Faul t a fantas y ? Will Williams succumb to Powell? Is t _h ere now , has there ever been o r will there be a subduction zone on the far South Coast? Spend y our $10.00 now and be well-prepared for the Bermagui Field Conference .

Don't let y our plans be overturned !

STRUCTURAL ANALYSIS TECHNIQUES AND APPLICATIONS IN THE BROKEN HILL DISTRICT - FIELD COURSE, MAY 1-7, 1983 The GSA-sponsored field course in structural analysis techniques at Broken Hill has come and gone, and the twenty-three participants have returned to their far-flung corners of the continent, there to amaze and mystify their colleagues with talk The course of Mohr circles, reciprocal strain and Fry diagrams. was ably led by Bruce Hobbs and Chris Wilson, with the help of graduate students from Monash and Melbourne, and was based at the Silverton Youth Camp, some 20 km from Broken Hill (an ideal The participants location for a field-oriented course). represented~ broad spectrum of geology in Australia, in terms of geography (all states and the ACT were represented), affiliation (about 50% industry, 25% government organisations and 25% students and Academia), and experience (ranging from undergraduates to 20 years plus).

Additional talks were given by Mike Sandiford (Melbourne) on high-grade metamorphism and deformation in Enderby Land, and Christian Teyssier (Monash) on deformation in the Arunta ·complex.

Application of theory to the field situation was largely by means of discussion and observation on the outcrop, with a couple of short and informal exercises thrown in - perhaps a more formal mapping exercise could be included in any future courses.

The course was well run and, I believe, well received by all of There was a good balance between field and us who were on it.

BOOK REVIEW Elena GRAINGER : The Remarkable Reverend Clarke times of the father of Australian geology .

Ox ford University Press 1982 , $24 . 99 .

The life and Melbourne

By any reckoning, the Rev . W.B. Clarke earned an honoured place among Australia's geological pioneers. His elucidation of stratigraph ic order in the Sydney Basin alone would have guaranteed remembrance but, in addition , there was the wide-rangin g goldfields reconnaissa nce, work as collector and compiler of information on the sedimentary formations of New South Wales, and much else . For many y ears Clarke was practically a one-man, honorary geological survey in the colony . And while doing all this, he was parsons to unneglected parishioner s . Clarke indeed was a remarkable man clergyman, schoolmaste r, geologist, museum curator, poet, sketcher, and the list is unfinished - and remarkable it is that his career has only now received book-length treatment.

Mrs Grainger argues, reasonabl y , that to do justice to all of Clarke's manifold activities would require a tome of unpublishab le length . She has chosen to concentrate on her subject's 'personalit y ' and his career in science; it seems she gained an enthusiasm for geology from her late brother H. G. Raggatt . Sadly , she shows in this book that enthusiasm and understandi ng do not always run together . In matters relating to Clarke's origins, boyhood and education, to his clerical career in England and Australia and to his family life , Mrs Grainger is a confident and generally reliable She paints a fair picture of the man's sensitivity to guide. criticism and inclination to self-defenc e. She does well also to emphasize the continuing financial problems against which Clarke had to struggle . It makes his achievemen t the more impressive.

There the Turning to science Mrs Grainger loses her touch. solecism of the title points . Mrs Grainger shows few signs of knowing what geological discovery entails . Errors either of judgement or fact lie through her te x t, traps to the unwary .

Presumably intended to introduce Clarke's science, a chapter on The Birth of Geology pays no attention to William Smith and stratigraph y, and treats Hutton and Werner misleadingl y. Yet Clarke's main interests were stratigraph ical . He even claimed to be a disciple of William Smith , a fact noted b y Mrs Grainger who quite overlooks the pre-Smithia n lithologica l nature of the argument used by Clarke for the Sydney Basin until he was taken to task by W. S . Macleay.

It may be added that Macleay's intellectua l influence on Clarke is not seriously pursued; Mrs Grainger seems content to accept Macleay at his own casual estimation, a 'dabbler ' in geology. Outlining Clark ' s work in the Hunter Valle y , the author fails even to notice the section at Stony Creek that convinced Daintree (not sent b y McCoy asp . 226 would have it) in 1863 the order wasas Clarke claimed. Nor is the frustrating dispute between Clarke and McCoy adequately e xplained. One sees there little evidence of the questing 'free spirit' Mrs Grainger finds in Clarke. To claim boldl y that Clarke believed his coal - bearing succession was of Permian age is to ignore the hedging so apparent in Sedimentary Formations , as re v ised just before h i s death. Others, later, 19

establish the age, and the occurrence of late Palaeozoic glaciation .

Yet to argue, as Mrs Grainger does, that such glaciation was unknown in Clark's time sets aside Daintree at Bacchus Marsh in 1866, the evidence from Nagpur in 1872 and much earlier discoveries in the boulder beds of Talchir.

In discussion of gold discovery and the gold surveys, Mrs Grainger takes the protagonists at their own self-justificatory valuations. Governor Gipps's alarm at Strzelecki's find (p . 163) sits strangely against official publication of the news in London.

Why, again, if Clarke found gold in 1841 did he wait some years before telling his mentor Adam Sedgwick, with whom he was in regular geological communication? Mrs Grainger's story about Strzelecki showing Murchison his Australian samples in Berlin is wildly wrong. Strzelecki was still here when Murchison returned from his second, and last, visit to Russia.

The list of lapses could go on, and on. A chapter on Clarke and Darwin's The Origin of Species is short on critical detail as to how Clarke responded to evolutionary argument. He seemed more concerned with Darwin as geologist. And the reference to Lamarck is a travesty of that scientist's view.

This is a book one wanted to recommend. Geologists ought to be informed how scientific knowledge accumulated and about those who contributed to that store. The present work, alas, will not help them much. Carelessly proof - read, uncritically written where it ventures into science, the book as a whole brings little credit to publisher, author or the Literature Board that subsidized the research.

A SUPERB START TO A NEW SERIES OF MONOGRAPHS Edited by J. Roberts and P.A. Jell.

Dorothy Hill jubilee memoir.

Association of Australasian Palaeontologists, Memoir 1, 371pp. $20 ($12.50 to subscribers to Alcheringa and Members of the Geological Society of Australia).

To festschrifts and commemorative volumes there would seem to be no end, but now we have a jubilee volume in honour of Dorothy Hill, global authority on rugose and tabulate corals and sage on so I will not dwell on many things to do with Australian geology.

A brief biographical details as my fund of Hilliana is not great. account is given in the introduction to this volume by her old they provide a useful students Bruce Runnegar and John Jell; bibliography of her publications, and a listing of salient events That she is worthy of a full-scale biography was in her career . evident from the anecdotes - invariably benign, often bordering on the droll (selected for the occasion!) - from old colleagues and students at the meeting in her honour organised by the Association of Australasian Palaeontologists in Brisbane on 9-10 September 1982.

I must silver, golden or diamond jubilee or somehow all three? admit that the first jubilees that came to mind were ecclesiastical those 25th year episodes in which remission from the penal ones: consequences of sin is granted upon repentance (this didn't seem to figure in the case of Dorothy Hill!), or those ancient Judaic ones wherein every 50th year bondmen were set free, fields were left untilled (again inappropriate!) and there was much blowing of It was in trumpets and general jubilation (highly appropriate!). honour of her 75th birthday, but 1982 was also the golden jubilee of the award of her Ph.D. Dorothy Hill's impact on Australian geology and palaeontology as teacher, editor, administrator, researcher and enabler of • She did not have the opportunity research has been remarkable. to enchant tens of thousands of first-year students the way the legendary Joel Hildebrand did for chemistry or to galvanize the teaching of first-year physics the way Richard Feynman did at Caltech and thus affect a whole scientific generation - or generaThe potential to do so seems always tions as Joel Hildebrand did. to have been absent in our universities where geology has been the Or is it because we have left this Cinderella of the sciences. task to junior academics, too rarely dragooning our best teachers, our charismatics if you like (Feynman is a Nobel Laureate), into Dorothy Hill too was inspiring as the first-year lecture theatre. a teacher, encouraging the scientific qualities of imagination, originality, judgement and curiosity in her students, especially the large flock of postgraduate students who came under her influence; Her influence many of them are contributors to this jubilee volume. continues, she is still publishing, and we hope that like Joel Hildebrand she will still be publishing in her 100th year - several jubilee and centenary volumes later!

What are the contents?

Old students and admirers have contributed 22 papers spanning many fields of palaeontology - vertebrate, invertebrate and palaeobotanic.

Our newest earth sciences academician, Ken Campbell, with R. E. Barwick, takes a long and characteristically careful look at the early evolution of dipnoan fishes.

They take issue with prior cladistic (parsimonious) interpretations, reemphasizing the importance of functional analysis and the need to arrive at 'internal consistency between the interpretations of a range of structures and the final inter-related pattern of structures'.

Their paper is exemplary in having done just that.

In the other vertebrate paper, John Long continues his monographing of the extraordinary Late Devonian (Frasnian) fish fauna from Mt. Howitt in Victoria with a meticulous description and functional interpretation of a new genus and species (placed in a new family) or deep-bodied acanthodians, Culmacanthus stewarti.

There are four palaeobotanic papers: a neat and elegantly illustrated paper (by Geoff Playford) on the miospore genus Geminospora specifically focussed on its widespread species~- lemurata, indicator of sediments close to the Middle Devonian-Late Devonian boundary; an evaluation by Clinton Foster of the functional morphology of the Late Palaeozoic pollen genus Jugasporites in which it is shown to have been operculate, restricted to Euramerica and that Australian records are incorrect; a judicious study by John Webb of a new genus and species of mid Triassic plant that may have been a marattialean fern; and a study by Murray Dudgeon of 17 form-species of presumed proteaceous pollen from the mid Eocene of the Yaamba Basin near Rockhampton.

Predictably, more than half the Yaamba pollens are new; .this is an obvious reflection of the pronounced southern bias in the spectrum of information to date on Australian Late CretaceousCainozoic palynology.

There is an especially tantalizing lack of information, particularly macro-floral, for the Late Cretaceous-Palaeogene that leaves us with mere speculation on the sequence of floral events that followed on the separation of Australia from its neighbours to the east (New Zealand, New Caledonia, etc.) and the early stages (until broadly Eocene times) of immigration from the north.

Two-thirds of the volume consists of contributions on invertebrate palaeontology ranging from sponges and archaeocyathans to trilobites and echinoderms.

One of the editors (Peter Jell) is involved in papers on three of these groups: a paper on Cambrian Sphinctozoa (with John Pickett), one on Ordovician trilobites (with W. T. Chang) and the third describing five bizarre echinoderms - two species of an outlandish new genus of ophiocystoids, a new genus of blastoid and two new genera of carpoids, study of which has induced Peter to propose two new orders.

One of these, appropriately for this volume, is the Hillocystida, based on Hillocystis gen. nov., a line-drawing of whose type species~- atracta sp. nov. is the elegant motif on the cover of the volume.

Four contributors are from boreal regions.

Bill Oliver discusses the presumably parasitic 'worm' tubes found in Devonian rugose corals.

Guo Sheng Zhe describes an Early Ordovician receptaculitid from China, pointing out similarities to archaeocyathids; he inclines to the view that archaeocyathids and receptaculitids were closely related.

Jim Sorauf discusses the exquisite preservation of skeletal structure in the Permian rugosan Timorophyllum from Timor.

Colin Scrutton presents an exemplary study of protocorallite ontogeny, corallite increase and colony development based on serial grinding and peeling at 0.1 mm intervals or less of a species of the Devonian rugose coral Phillipsastrea.

The last decade has witnessed a blizzard of new information of varying relevance about the earliest mollusks, much perhaps bordering on the trivial for an outsider or bystander.

In 'Molluscan phylogeny revisted', Bruce Runnegar attempts tidying up the resultant minor chaos of ideas and assertions about the many lineages of cambrian-Ordovician mollusks - he suggests 19 lineages in his latest count.

The result is information-packed, urbane and affable; I look forward to his next visit!

FIELD WORKSHOP ON GRANITOIDS, RELATED VOLCANICS AND MINERALISATION, Thredbo, New South Wales 13-16th February, 1984 Following informal discussions at the Sixth Australian Geological Convention a four-day workshop on granitoids etc. will be conducted

by Bruce Chappell and Allan White in the heart of S- and I-type country.

Emphasis will be on outlining recent advances in granitoid etc. studies, areas of current agreement and disagreement, and most profitable avenues of future research.

Themes to be discussed include (i) the role of restite in granites and volcanics; (ii) mechanical properties of granitic liquids and crystal mushes; (iii) water in magmas and tlE link between granite solidification and metal concentration .

Two full day and one ½-day field trips are scheduled .

The Thredbo Alpine Hotel conference centre has been booked and all-up costs including possible mini-bus hire will be $200.

As a deposit is required by the hotel prior to the workshop, firm expressions of interest must be received no later than the end of August contact BRIAN OVERSBY, c/o BUREAU OF MINERAL RESOURCES, P.O . Box 378, CANBERRA CITY, A.C.T. 2601, phone (062)499286.

Please also indicate if transport could be provided and for how many (total including driver) .

Any person willing to contribute structured material, either as a formal talk, to a less formal round table discussion, or in a poster-type format, should submit an outline.

continued from page 22 Mac Dickins examines ·the Fermo-Triassic life crisis concluding that climate and sea-level change were pivotal factors.

The evidence he presents seems fair enough but, as with all life crises from Cambrian to Cainozoic with the possible exception of the terminal Cretaceous event and o f course the latest anthropogenic one now unfolding, the evidence is circumstantial and not tightly constraining as to interpretation.

Ordovician faunas are described from southern Tasmania (Clive Burrett et al.) and the Townsville hinterland (Bob Henderson).

The usefulness of the SEM for new perspectives in bryozoology is demonstrated by a study of regeneration of calcification in the Adeonidae (Robin Wass).

The t ype species of the widely distributed Permian brachiopod Taeniothaerus is redescribed (Susan Parfrey), and the structure and function of e x othecal tissue in Somphocyathus and allied archaeocy athans is pondered (David Gravestock ).

A rev iewer is supposed to have a mean streak and fling a few mudpies, but I can find no cause for any thing but praise for this volume - for the editing, the lay out and the speed with which it was produced .

Two more memoirs are already in the mill: a monograph on the Archaeocy atha from the lower p a rts of the Lower Cambrian carbonates o f South Australia by David Gravestock, and a collection of papers on Mesozoic dinoflagellate biostratigraphy of Australia.

Rumour has it that both will be ne a t little Mercedes vo lumes - like this one!

In Search of Mineral Wealth The South Australian Geological Survey and Department of Mines, 1883-1944. Bernard O'Neil. Special Publication No. 2. S.A. Department of Mines and Energy, $16,95.

The reader in search of information will be well-served by this book. O'Neil has dug deep into the archival sources of South Australia and brought up a spoil heap of considerabl e proportions .

His plan of operation has been simple - a few exploratory costeams to examine the weathered zone and then a shaft, sinking deeper and deeper into the wealth with an occasional exploratory drive or cross-cut never venturing too far from the safety of the main haulage.

Unfortunate ly in as far as the information tells us O'Neil has not completely understood the geology of this rich lode. He has assumed it was a classical vein-type deposit, whereas he seems to have been working with a patchy porphyry copper. The result has been the production of a considerabl e amount of gangue along with the ore.

O'Neil has been given charge of the developmen t of a mineral deposit of considerabl e dimensions, which exceeds his practical experience.

Sound theoretical training is apparent in much of his approach but one feels he would have been all the better for a few years on some smaller mines where the structure was easier to understand.

It is only fair to Bernard O'Neil and the South Australian Survey that I translate the above metamorphi.c al statements. This book is a meticulous account of the official story of the South Australian Survey and Department of Mines to 1944 based largely on a determined pursuit of ministerial and departmenta l documents. While it is no doubt true that political policies and ministerial attitudes greatly affect the direction and influence of a department the personality of the departmenta l officers is, I believe, what ultimately decides its character. O'Neil has certainly sensed this but he hasn't got it over as he might have. Ministers of Mines of no more than a few weeks duration are granted space while H.Y.L. Brown, a fascinating fLgure if ever there was one, still remains a shadow; and R.Lockhar t, L. Jack, L. Keith Ward and the enigmatic Dr. Basedow could all do with more flesh.

Clashes between personaliti es such as Ward and Mawson, Ward and Basedow are only touched upon and never explored in depth.

The strength of the book lies in the meticulous documentati on of the official files, the mark of a dedicated and competent historian.

However, there are clear signs that O'Neil has been overawed by the geology, and the uninformed reader would be in some doubt as to just what Brown and his associates did when they went into the field for so long.

The book is beautifully produced and well illustrated (although 4 nearly identical HYLB's is a bit much!) including fine colour reproductio ns of the series of state maps which have appeared since the inception of the survey.

25

In telling his story O'Neil hasn't been a ble to decide whether to tell it from the view of the administration front office or as the underground manager saw the pro blems. In too many cases we are given the above-ground point of view, and it is much less in t eresting than the way a mine really develops. He has left too many important men stuck in an adit.

Perhaps in a few years O'Neil should return to the scene of his labours and review it once again bringing the story up to the 1970s.

It may prove to be a Roxby Downs.

This is an important book for those interested in the history of geology and mining in Australia and it will be a valued reference on my book shelves.

GEOLOGICAL SOCIETY OF AUSTRALIA INCORPORATED NOTES ON THE ACCOUNTS AS AT DECEMBER 31, 1982 1.

ACCOUNTING METHODS

(a) Centralised Accounting;The Society does not practise centralised accounting procedures and consequently, the Council Accounts presented here exclude the net assets and results of Divisions and Specialist Groups. (b) Publications on Hand:Publications on hand, which include past issues of the Journal, are stated at the lower of cost and estimated net realisable value. (cl Depreciation:Depreciation on furniture and office equipment is provided for in equal yearly instalments so as to write-off each asset progressively over its estimated life.

THE BALLAD OF B.M.R.

- THE OLD AND THE NEW

Down by the lake stood the old B.M.R. That sent out the surveys both near and far In deserts and in swamps, in mountains and in plains, In drought or dusty weather, floods or heavy rains.

Crack go the hammers, crack, crack, crack; As we knock off the rocks along the old bush track.

The going might be rough, but we got the data in, And published it in map sheet, Report or Bulletin.

In Land Rovers and Inter Trucks, we combed the countryside; In 'choppers too, geologists and gravimeters ride.

We took out magnetometers in aeroplanes and ships, And lived in tents and caravans on many field trips.

Crack go the shots, boys, crack, crack, crack; Start up the recorder as the waves come back.

The going might be rough, but we got the data in, And published it in Record, Report or Bulletin.

ASTEC looked us over, and said 'You'll do Research; With mere gathering data you'll be left in the lurch.

Publish or perish in the B.M.R.'s new· role Academic standards will apply upon the whole."

Churn out the papers, write, write, write, For the refereed journals, keep that aim in sight.

No more the Record, Bulletin, Report; Now we do Research, don't you know they count for nought.

Down by the lake the new Bureau stands, Recruiting research scientists from near and foreign lands Four Research Divisions and the R.A.D., And plans for campus buildings, though we don't know where they'll be.
