PRESIDENT'S PAGE

A sma l l item o f busine ss but with p ro f ound implicati o n s emerged at t he Perth Coun c il, and is i n d a nger of es c aping o ur attention.

The Society, through a t least one of its Divisio ns recently co-sponsored a sympo sium on Cainozoic Evolution of S.E. Australia.

The organisers are commended on their enterprise and skill in s taging what was obviously a most s uccessful symposium, and thi s is precisely the type of activity the So ciety should e ncourage.

An intere s ting situation arises because the s ymposium finished with a modest cash surplus.

Perhaps it would have been even more interesting if it finished with a d e ficit!

The question now arises to whom does this money belong?

Council decided against establishing a Standing Committ ee on Cainozoic Studies to administer this money, and there the matter rests.

We can confidently expect that similar situations will re-occur.

The Society simply has no administrative machinery to deal with these situations.

We have formally adopted a procedural guide for conventions which specifies that the incorporated body through its Federal Executive takes responsibility for surpluses or deficits.

Significantly, the la s t three major conventions (Fourth and Fifth Conventions, and the Archaean Symposium) grossed surpluses close to $30,000.

Before anyone yells "rip-off" - let me say that all symposia should be self-funding, and the size of the surplus depends on the contingencies and thresholds that are required by prudent planning.

All these symposia were funded through modest registration fees and represented excellent value for money.

Even with national events there seems to be some reluctance for organising committees to see their wellearned money channelled into "consolidated revenue".

For regional or specialist events this reluctance may be more ma nifest as it raises the spectre of "central funding".

However, I believe the Society needs to expand its Procedural Guide to ensure that arrangements for staging regional and specialist symposia are formalised, and that some pre- arranged formula is e s tablished for handling surpluses or deficits, particularly where co-sponsors are involved.

Perhaps we should look at establishing a Special Fund into which all surpluses are placed.

A register could be kept in which are recorded the amounts and sources of depo s its, and the organising committee's recommendations on how this money should be used.

The fund should be available for any Society-sponsored event for such purposes as initial floats for further meetings, invited speakers and publication of proceedings.

This fund could be expected to grow to the point where finances no longer constrain our publication policies.

De cember 5, 1981.

EDITORIAL Correspondence and phone calls from many parts of Australia make me more aware than most members of the extent of the activities of the Society and its individual members in promoting the profession of geology.

The success, or otherwise, of such efforts depends largely on the energy and enthusiasm of particular secretaries and local committees and is a consequence of the determination of Society members over the years to resist, as far as possible, centralisation of the Society 's affairs.

Despite some obv ious drawbacks, the passing of executive management from d ivision to division ensures a freshness in approach and a wider involvement of members in guiding the Society's affairs than might otherwise occur.

Dennis Gee in his President's page comments on one success story - the accumulation of funds from various conventions in recent years - and makes a very practical suggestion on how these funds should be handled.

While modest profits from confe r ences are to be app l auded, much of it comes from registration b y nonmembers.

The Society would surely benefit more by having a regular income from a larger number of members.

If y ou, as a member, feel t h e Society h as someth i n g to offer, why not tell y our non-member friends?

Better still, the direct action of giving a membership form may yield more rapid results.

Despite the fact that registration fees for the Society's Perth Convention were kept low for students, and that the Society offered to help with finance for travel there were too few students enrolled at the conference.

W.A.I.T. students told me recently that registration at the conference was too expensive for them.

It is essential that such potent i al (future ) members should be encouraged to join the Society.

We certainly aren't working hard enough at it at the moment.

Perhaps some of the surplus conferen ce funds could be put to good use in encouraging student membershi p .

Any constr uctive ideas would be welcome.

Ron Vernon Honorary Editor JGSA

Sir: The presidential address by Colin Branch to the recent Australian Geological Convention (Australian Geologist, No. 36) raised some pertinent matters concerning the public's impression of geologists.

Since the public knows nothing about academic geologists, the popular image is that of the industry geologist, so this letter is mainly concerned with them, although certain criticisms apply also to some geologists of the academic persuasion.

Suggestion that geologists speak publicly about issues of public concern has one problem : the public concern is usually opposed to the interests of company geologists.

The average Fred Nurk is suspicious of these geologists, and rightly so, since they are highly paid professionals and hence are members of an elite class which has vested interests in one of the most powerful groups in this country the mining industry.

"Where are our Harry Butler's of geology?" asks Colin Branch.

Part of the answer is that Harry Butler is a conservationist, geologists are not.

Company geologists have shown that they have no concern for our environment.

When did they ever speak out against the mining of uranium, the incursion on aboriginal land by uranium and oil prospectors?

When did they speak up against proposed oil exploration on the Great Barrier Reef?

When did they oppose the building of dams in south-west Tasmania?

When did they oppose limestone quarries in areas containing important cave systems, as at Mt. Etna in Queensland and South Marulan in N.S.W.?

When did they speak out against quarries and mines in national parks, or beach sand mining at Myall Lakes?

When did they speak out against the exploitative role of large oil and mining companies in third world countries?

In my (undoubtedly biased) opinion industry geologists are either more interested in money than in these issues, or they don't have the courage to take a stand against the company viewpoint.

If several geologists pursued political careers their contribution to the development of our nation would be equal to that of any politician - approximately zero.

The best contribution geologists can make is to develop a social conscience and start considering people rather than profits.

GEOLOGY IN COLOUR IS BETTER? Barry J. Cooper Most geologists do not make a habit of commenting However I will about the quality of their publications. make an exception on this occasion due to the nature of the response to one of my efforts.

"Eocene to Miocene Stratigraphy of the Willunga Embayment" was published in late 1979 as Report of Investigations No. 50 of the Geological Survey of South The monograph essentially deals with the Australia. geology of a small region 30 km south of Adelaide.

Fifteen colour photos were dispersed through the first 30 pages of text in addition to a coloured front cover.

The coloured illustrations are the reason for this All comments from geologists about the monograph note .

Most believe have invariably made reference to these. that the geology is simply better illustrated with colour Some people also rather than black and white photos. recognise the value of colour illustrations in future field studies of an area either for research or teaching.

Two years after issue of the Willunga Embayment monograph, I appreciate that colour illustrations do provide better documentation of geological data.

Amongst the plethora of geological journals available And where today, very few encourage colour illustration . journals do publish colour, the author usually bears resWith the response ponsibility for the additional cost. to my colour illustrated paper in mind, I think there may be a need if not a demand for more colourful geology journals.

Could the journal of the Society be more successful if it insisted on colour illustrations as normal practice?

Would geology researchers, teachers and general professionals be more attracted to a journal which publishes in The cost of production of a colour journal would colour? definitely be higher but this factor would be reduced if there were simply more subscribers.

Certainly the success of a journal is determined not only by presentation, but also by the nature of its And the best papers will most likely be contents. attracted to a journal which publishes using the best and most versatile methods.

When the Society reassesses the role and purpose of its journal in the near future, I suggest that the Society consider the possibility of producing a top class colour illustrated journal even if it means seeking ~upport from outside sources and placing careful limits on the size of Such an undertaking certainly involves the production. risk, but it is certainly worth considering.

"Beds" or "beds"?

The term "Beds" was originally recommended by the Australian Code of Stratigraphic Nomenclature for a sequence of strata whose thickness and lithology were It has been a useful term in areas incompletely known. where insufficient detail has been mapped to permit Many such "Beds" definition of formations and groups. units have been erected in Australian stratigraphy.

Under the provisions of the International Stratigraphic Guide, however, the term "Beds" now has a very different connotation: it describes a sequence of strata which are very well known and which are comA "Bed" is pletely defined (I.S.G., Section 5.C.4). now a named distinctive layer in a member or formation, e.g. Baker Clay Bed; and a sequence referred to as "Beds" is a continuous succession of several such Such a sequence would be well enough known to units. be given member or formation status, e.g. Marcus Limestone Beds.

In view of these provisions of the I.S.G. it is now necessary to reconsider the nomenclature of Australian units that have been defined as" ... Beds".

There are several possible ways of adapting their nomenclature to the new standard:1.

If such units are only being referred to in literature, without further field work being done, their names should be quoted informally, e.g. "Laurel beds", and the units should be regarded as informal units.

2.

If the top and the bottom of such units can be nominated as boundary stratotypes, and the intervening strata are well enough known, it may be possible to formalise the unit and redefine it as a formation, e.g. "Laurel Formation".

3.

If the unit contains one or more defined formations as well as otherwise undefined strata, it may be definable formally as a group, e.g. Laurel Group, provided that the upper and lower boundaries The Australian Code restricted can be specified. the term "Group" to a sequence consisting entirely of named and defined formations, but the I.S.G. allows it to be applied to a sequence which includes undesignated strata.

The Stratigraphic Nomenclature Committee is opposed to the proliferation of informal names, and considers that units described as" ... beds" should not be estaIt recommends that authors should, as blished lightly. far as possible, avoid using such informal nomenclature.

It is preferable either to define the unit as a formation or a group, or to avoid using a geographic name altogether.

7

Equal caution should be exercised in establishing It a group without any constituent defined formation. is the formation which is the primary building-block of stratigraphy, and initial investigation of any area should aim at establishing units of this category.

All of these topics are considered in the second draft of the "Field Geologist's Guide to Lithostratigraphic Nomenclature in Australia", which is now available for perusal from Conveners of Divisional Subcommittees of the Stratigraphic Nomenclature Committee.

SUGGESTED OUTLINE FOR NEW MINERAL DESCRIPTIONS by the Commission on New Minerals and Mineral Names of the International Mineralogical Association* This "suggested outline" is largely based on a previous paper with the same title by Donnay and Fleischer (1970).

All Manuscripts that describe new minerals and new synthetic crystalline phases have a good deal in common.

Nearly all the leading mineralogical journals now require that proposals of new mineral names be approved in advance by the I.M.A. Commission on New Minerals and Mineral Names.

To save the authors and the referees time and trouble, we are listing below the subtitles followed by brief descriptions that the authors should attempt to deal with whenever possible.

It is evident that not all the data suggested can be obtained, especially on small samples, but enough data must be provided to characterize the mineral unambiguously; as a rule this will require, as a minimum, a quantitative chemical analysis or some other proof of its chemical individuality, X-ray powder data and basic optical data.

The details under Occurrence, Storage of type specimen and Name . below are always required.

In general, polytypes should not receive individual mineral names, but should be designated in accordance with the "Report of the I.M.A.-I.U.Cr. Joint Committee on Nomenclature" (Bailey, 1977).

Exceptions to this rule may be considered if supported by evidence of striking differences in the properties of the polytypes involved.

New members of the pyrochlore or amphibole groups should be named in accordance with the schemes proposed by the subcommittees of the Commission (pyrochlores Hogarth, 1977; amphiboles Leake, 1978).

The same holds for new members of mineral groups the classification and nomenclature of which may be reconsidered in the future (pyroxenes, micas, zeolites, etc.).

Other guidelines, highly recommended and in no way conflicting with the present suggestions, are formulated by the Commission on Crystallographic Data of the International Union of Crystallography (Kennard et al., 1967) and by the Commission on New Minerals and Mineral Names of the All-Union Mineralogical Society of the Academy of Sciences of U.S.S.A. (1975, 1977).

The -criteria of the Soviet Commission are recommended in particular as far as polymorphs (especially for Order-Disorder polymorphs), solid solutions, mixed layer minerals, metamict minerals are concerned.

The requirementsfor amorphous minerals are currently under consideration.

Authors proposing new mineral names should read carefully the statement by F. Permingeat (approved by the I.M.A. Commission) in Hey et al. (1961). *Submitted by E. H. Nickel, Australia's representative on the Commission.

PARTICIPATION OF TERTIARY TEACHERS OF EARTH SCIENCES IN AUSTRALIAN MINERAL FOUNDATION COURSES The Council of the Australian Mineral Foundation has accepted.my representations that there is much to be gained by an increased participation of academic geologists from tertiary teaching institutions in the courses of the AMF. The majority of courses offered have had little or no participation from academic geologists mainly, it is thought, because of the significant cost of course fees coupled with transport and living expenses while attending However the Director of the AMF, Dean Crowe, the c o urses. is prepared to do what he can to assist genuinely interested academic earth scientists in attending appropriate If you are teaching earth sciences in a tertiary courses. institution and you have a burning and real desire to attend an AMF course but lack supporting funds, then you should apply to him (Mr. D.

Book Reviews Biogeochernical cycling of Mineral-Forming Elements edited by P.A. Trudinger & D. J. Swaine Elsevier, Amsterdam, 1979.

US$97-50 Oddly enough this book does not seem to have received a review in any Australian journal despite its editorship and its considerable Australian content.

Some 25 authors have looked at the behaviour in nature of seven major element cycles (carbon, phosphorus, iron, manganese, sulphur (sulfur for the mods), silica and uranium), with major emphasis on carbon and sulfur.

The purpose of the book is to 'review current knowledge of the major biological processes which are involved in these geochemical cycles and which influence, directly or indirectly, the formation, dissolution and transformation of minerals.'

Specific minerals have been selected on the basis of their quantitative or economic significance.

As might be expected this equates somewhat closely with the available biogeochernical data.

The opening chapter by the editors (assisted by G. W. Skyring) is an excellent summary of the complex relationships which exist between biochemical, chemical and physical processes today and which have been active during geological time.

They acknowledge the limitations in present knowledge of many aspects of the subject, but point out that there are likely to be major advances in the corning decades as the many new technological tools (e.g. satellite imagery, electron and ion probes and computer-assisted analysis) come to be fully utilised.

The two last chapters look at the practical aspects of the topic in the context of agriculture (V. J. Kilmer) and industry (B. J. Skinner), the latter being concerned mainly with the availability of minerals through mining and previously published in the American Scientist.

These essays are, of course, complete in themselves and make interesting and fruitful reading as they underline the value of the various lines of research described in the earlier chapters, which have been followed in the past and which are needed in the future, in view of man's dependence on the various mineral cycles.

The book has a useful glossary of terms and each chapter ends with copious references up to 1978.

It is interesting to find virtually no reference to the classical geochemical texts by Goldschmidt, Mason, Fersrnan and others, and Breger's more specialist work on organic geochemistry seems to be also forgotten.

Such is progress.

This book contains an immense amount of information which will be useful to a wide variety of researchers.

This is both its strength and its weakness.

I know it has been used by speleologists, agricultural scientists and economic geologists.

hide it on the biology shelves so you might miss i t.

The volume is the third in a series 'Studies in Environmental Science' which covers a broad spectrum but there can be little if any link between the volumes.

Elsevier's usual high prices preclude its presence in most individual research libraries, but keep it in mind when y ou hav e a biogeochemical problem.

This book cov ers a wide field indeed and does it e x tremely well.

The book is divided into two sections.

The first comprises thirteen sets of maps of the Cainozoic and Mesozoic at 20 Ma intervals, including a set for 10 Ma, and is essentially an updated version of the map book published b y Smith and Briden in 1977.

The second section comprises nine sets of maps at 40 Ma intervals with the oldest at 560 Ma (early Cambrian).

The authors admit in their introduction to this second section that their Palaeozoic maps do not gi v e complete or necessarily unique solutions to the problems.

A comparison with the Palaeozoic maps produced b y Scotese et al. (J. Geol. 87, 217-277) reveals a number of significant differences, relating for example to the number of separate continents and microcontinents recognized, and the weight given to palaeoclimatic or faunal evidence where it appears to conflict wi th that from palaeomagnetism.

The present authors a r e "unifiers" rather than "fragmenters" and also in most cases prefer the palaeomagnetic e v idence.

Chin a and Kazakhstan are as a result not treated separately, as I believe they should be.

It would hav e helped users judge the degree of uncertainty inherent in the maps if a s u ccinct summary of pro v isos had been supplied - e.g. the early Palaeozoic position o f Gondwanaland depends fairly heavily on data from Australian rocks magnetized re l atively weakly near the palaeomagnetic equator.

Appropriate to these days of heightened awareness of copy right the user is reassured by a note on the reverse of the title page that photocopy ing of the maps and their reproduction in research journals are permitted.

A valuable tool for global s y nthesizers, and a joy for lovers of palaeo-jigsaw puz z les.

JOINT G.S.A. - P.E.S.A. CONVENTION - THE EROMANGA BASIN A three day convention will be held on the above topic from 10th to 12th November 1982 inclusive, at the Australian Mineral Foundation in Adelaide.

The convention is designed to attract a wide range of personnel from academic institutions, geological surveys and private companies throughout Australia.

The Eromanga Basin is a large sedimentary basin of Jurassic to Cretaceous age, which extends over four states (N.T., S.A., Qld., N.S.W.).

Significant quantities of hydrocarbons, mainly oil, have been discovered in the sequence, and much more may lie undiscovered.

Today, intensive studies of all aspects of the geology of the basin are being conducted by a wide varie~y of organisations, and it is the aim of this convention to draw these groups together.

The G.S.A.-P.E.S.A. symposium has two themes: A. B.

Towards a Comprehensive Basin Analysis Hydrocarbon Potential of the Eromanga Basin

An invitation is extended for the submission of titles of contributions to be presented either as a paper or as a poster display.

Review papers are welcome, particularly those combining data from various states.

Persons wishing to receive future circulars on the conference should write to: "Eromanga Basin Convention" c/o D. Gravestock, Dept Mines & Energy, Box 151, Eastwood, 5063. phone (08) 272 5711

AUSTRALIAN CONTINENTAL REFLECTION PROFILING (ACORP) PROGRAM A Workshop on Deep Reflection Profiling, to which a COCORP representative will be invited, is being planned for early February 1982 at a venue to be decided. Limited funds to attend may be available.
