EDITORIAL
The recent proposal to split CSIRO and put part of it under the control of the Minister for Minerals & Energy in a new body including the Atomic Energy Commission and the Bureau of Mineral Resources caused apprehension to a great number of Society members, and many felt that the Society should have made some comment at the time.
The situation emphasises once again that the Society has a split personality, that of learned pedant, combined with go-ahead businessman, and isn't quite sure which way it should look or which mouth should speak or bite the hand which feeds it. Will it harm those of its members in government strongholds if it criticizes our great leaders, will it earn the plaudits of those on the other side of the situation? What effect will it have on the Society itself.
The political implications of the use of atomic energy, peaceful or otherwise, make it essential that it be kept separate from other mining and geological activities as far as possible. A repetition of the scurrilpus accusations made by politicians against David Rivett and the CSIR back in the 1940's is certainly to be avoided.
It is interesting that New Zealand made an almost opposite move many years ago by transferring the geological survey from the Ministry of Mines to the care of the Department for Scientific & Industrial Research (DSIR). I'm not sure what reaction there was amongst N.Z. geologists at the time, but it seems to have paid dividends since, for the geological work of the country.
The Bureau of Mineral Resources has been able to work for many years in a wide field of geology and it would be a pity to see it become a mere producer of data for short-term mining purposes. The mere fact that no director has yet been appointed (even at the miserable salary offered) suggests that it is being used in a political game. Things have likewise remained fairly quiet on the CSIRO scene.
It seems to me to be bad for the country as a whole, and certainly not good for the geological scie~ces. Perhaps we need an institute of geology which embraces the functions of the Bureau and the Mineral Investigation side of CSIRO, somewhat along the lines of the British Institute of the U.S. Geological Survey, but whatever we have should have some independence from the sort of political and other fiddling which has been taking place lately.
Perhaps the Society can't have a voice but individual geologists surely can speak for themselves. The Society, their own organizations or the politicians must be told what the individuals feel about what has been going on. It would even be good to know what has really been happening Does anybody have any facts on the present situation? This journals has so far received no comments whatever.
If we don't get off our tails soon and so something the future might be even less rosy than the present. Geologists surely believe their work ' is important. Why not tell the community that it is?
QUEENSLAND DIVISION FIELD CONFERENCE - 1975
The Queensland Divisiorls annual Field Conference was held over the Queen's Birthday long weekend, 14th to 16th June, in the Mt. Isa district. Daily excursions were conducted to the Duchess phosphate deposits, the Mammoth Mine at Gunpowder, and the Mary Kathleen open cut.
Of the 40 participants 25 (5 students) came from Brisba.,e and Toowoomba, 6 (5 students) travelled from Townsville, and 9 registered at Mt. Isa. This conference, perhaps even more than its predecessors, was a very successful gap-bridger, allowing academics and students, government employees and industry geologists to come together for discussion at the outcrop, as well as providing an opportunity for geologists outside the capital city to participate in Society affairs.
For the second year in succession the conference was run at a lossinflation catches up with us all. As usual the Division is indebted to the many companies who provided financial support, particularly to those companies whose properties were visited, and to Mt. Isa Mines Ltd. for the provision of accommodation for student participants.
The excursion guidebook, which includes geological descriptions of the mines visited and summaries of N.W. Queensland geology with some previously unpublished radiometric dating data, can be purchased from the Queensland Division Honorary Secretary (G.P.O. Box 1820, Brisbane, Q. 4001) at a cost of $4, postage included.
Sir:
Professor Prider is to be congratulated for offering his Honours students a 'Readi ng , Seminar and Language Course ' (Newsletter No. 6 , p. 10) .
In the School of Applied Geol ogy at the South Australian Institute of Technology we have as one of the stated aims of our first-degree course that 'graduates should have an ability to express themselves fluently, but concisely, both orally and in writing'.
To assist our students achieve an acceptable standard of scientific writing we provide both an external standard and editorial guidance. The Journal of the Geological Society of Australia is the standard to which all students are referr ed. The editorial guidance is offer ed in two ways.
1. First-year undergraduates are requ ired to write three reports during the year At least three weeks before each report is due they submit a draft report for preliminary editing of both scientific content and expression. This initial editorial guidance allows students to perceive the standards required without penalty. Students in s ubs equent years do not submit draft reports and their standard of expression i s i nc l uded in the report assessment , but they still receive detailed editorial comment when their reports are returned.
2. Second- year students undertake a first - term unit entitled 'Scientific Report Writing' similar to the course offered at the University of W.A. In addition, I give a short practical unit in critical geological editing, based on a course given by Mr K. A. Townley to geologists in the Bureau of Mineral Resources several years ago.
To achieve fluency in oral pre s entation, every student in second and third year presents a tu t orial each fortnight. Tutorial ses s ions are conducted under condi ti ons simi lar t o those a t a g eologic al congress, and str i ct time limits are ma intained for pre s entation. Each studen t' s performance is criticised (or prai s ed) by both staff and stud ents; some sessions are videotaped so that students may be self-critical.

Sir,
Having been faced with almost all the possible alphabetic permutations I have a great deal of sympathy for Mr. Ian W. Reid (Newsletter No 6) over his initial problems, and promise to continue, as far as possible, my practice of spelling out names, with the acronym in parentheses, the first time reference is made to an organization in publications of the 25th International Geological Conference (25 IGC).
However, I would like to warn Mr. Reid and other readers of a practice which has come to my notice and which could, if it becomes general, be as controversial as some recent bowling styles.
The ploy is to retain the acronym but to change the other letters of one or more of the words from whose initials it is formed. I will refrain from naming the one organization which I know to have done this, but alert readers who compare the Second 25 IGC Circulars with the Third (when it is published in March, 1976) will be able to identify it I ask you, Sir , is it cricket? It does seem to me to be most damnably like it .
A. Renwick Secretary - General 25th
INTERNATIONAL
GEOLOGICAL CONGRESS
Mr. Reid's appeal has struck a responsive cord. At least 35 such abbreviations appeared in the Society's last Council meeting minutes. I hoped to give a comprehensive list in this issue but the task has proved beyond me and is postponed to Newsletter No 8. Editor.
The Tasman Bridge disaster and consequent need to improve communications between the eastern shore and Hobart have made available a bonanza of bones. Widening of the Old Beach Road allowed the recovery of about 50 tonnes of rock containing the bones of Early Triassic fish, amphibians and reptiles (over 200 million years old).
The bones were discovered a little more than 10 years ago by Miss Helen Hughes (now Mrs. P. G. Quilty) and the rock containing them partly excavated by Dr. John Cosgriff during his tenure of a research fellowship at the Geology Department from 1964 to 1967 and subsequently by Dr. Cosgriff and Mr. T: Djiewa (Wayne State University) early in 1971. As a result of these activities which involved removal of about five cubic metres of rock, over five hundred fossils were recovered varying in nature from complete small specimens of freshwater fish to fragments of reptilian skull and limb bones and including complete and incomplete skulls and lower jaws of several amphibians. It is interesting to note that the fossil fish included lung fish. Three species of extinct genera of amphibians were described from this locality by er. Cosgriff in a Special Paper (149) of the Geological Society of America published during 1974.
The bones are contained in a bed of clay-pellet conglomerate, representing a gravel deposited in the channel of a small stream draining in an area of clay pans and silty and sandy flood plains. One may envisage an area, part of an ext~nsive river system, rather like the Channel Country of south-west Queensland today. Animals which lived in and near the rivers and ponds, died and their bones were swept, together with fragments of clay and silt, downstream during a flood to come to rest in the deeper part of the stream channel. Imbrication of the clay pellets indicates that the stream came from the north-west. The size (up to 40 ems) of the clay pellets indicates a stream of considerable velocity. The recent excavations have shown that the bed lensed out and passed into sandstone to the east as it did also to north and south along the cliffs of sandstone beside the Old Beach Road. The bones seem to have been concentrated near the base and the eastern margin of the gravel bed.
The fossils discovered to date allow some reconstruction of the life in and around the ponds and streams. Small conchostracans flourished in the ephemeral ponds and were eaten probably by small fish, themselves prey for larger fish. The fish were in turn pursued and eaten by amphibians swimming in the streams or lurking on the river banks. Fossi} excreta full of fish scales have been found in the clay-pellet conglomerate. Fish and probably some of the smaller amphibians were eaten by reptiles, a skeleton of one of which has been found in slightly younger beds on Knocklofty. This reptile was almost a metre long and the amphibians so far described from Old Beach were probably mostly 30 to 50 cm long. However, the recent excavations revealed one piece of bone about 15 cm long. The animal from which this came is likely to have been well over a metre long and such a size has also been suggested by Dr. Cosgriff for some of the amphibians.
The similarity of this vertebrate fauna to contemporary faunas in Western Australia, Antarctica, India and South Africa suggests close proximity of Tasmania and Australia to those other areas at the time. Oddly enough the Tasmanian fossils are also related to fossils which occur in Spitzbergen and Greenland, suggesting land connections between the northern and southern continents.
The prospects of getting more fossil material from the clay pellet bed to allow a more detailed reconstruction of the fauna and relationships of the Early Triassic has been attractive since the deposit was first worked. It has, however, also been dimmed by the necessity for removing 10 to 15 metres of solid sandstone overburden over a length of 30 metres and to an unknown distance into the cliff. As the bed itself is only about 0.6 metres thick, something like 15 cubic metres of unfossiliferous sandstone would have to be removed for every cubic metre of fossiliferous roe~, the latter containing about 100 bones or bone assemblages per cubic metre. Such an undertaking was beyond the financial resources of the Geology Department. We had, therefore, made an arrangement with the Brighton Council that when the planned widening of Old Beach Road took place we were to be kept informed so that we could collect any fossiliferous material thus made available. The Tasman Bridge disaster changed that arrangement.
In mid-January we heard that the Old Beach Road was to be widened immediately. Negotiations between Mr. N. Kemp, Mr. Banks and Professor Carey on the one hand and the Public Works Department and Police Departments on the other resulted in an arrangement whereby we could collect and remove the fossiliferous material and the P.W.D. give some help with bulldozers, bucket loaders and trucks. The balloon went up earlier than expected and by January 23rd we knew we not only could but had to operate in strength on the following Sunday, January 26th. On that day twenty people from the Museum, the Geologica l Survey, Matriculation Colleges, the Education Department and from the Anatomy and Geology Departments at the University with help from other interested people chopped, wedged, blasted and otherwise broke rock, carried it and loaded it. Few bones were seen but a couple of jaws with teeth and some other bone fragments were sighted. A twelve tonne truck well-loaded was sent back to dump its load on the University grounds on Mt. Nelson Later, either the quality of the rock improved or people got their eyes in and acquired collecting skills. The following Sunday over thirty tonnes of fossiliferous material was removed and on later occasions about another ten tonnes, so that now approximately fifty tonnes of fossiliferous material has been stored a.t the University. At about 100 specimens to the tonne, there is in prospect a collection of about 5,000 specimens , a rich, one of the richest, collections of vertebrates from beds of that age or any age The obvious bones are stored in the rock store at the Geology Department. Several hundred such bones have been collected and include probably a couple of dozen recognisable jaw bones as well as skull, vertebral and limb fragments, some of them or considerable size.
Thus this inter-departmental, inter-institutional rescue operation h?s allowed the recovery and preservation of a veritable bonanza of ancient bones, a bonanza to be exploited, it is hoped , through study by students from this University and State as well as by overseas experts. Associate Professor Cosgriff, now of Wayne State University, v isi ted the Univers ity during April to examine the new material, advise on work on it and lecture on fossil vertebrates , especially the groups present in the Old Beach collection, to geology and other students and other interested parties.

PERMIAN VALLEY GLACIATION IN THE BENDIGO REGION, VICTORIA.
Mr. Frank Robins of Bendigo has spent over twelve years investigating the Permian glaciated region between Bendigo and Heathcote. His particular interest has been the glaciated pavements and in conjunction with his friend, Mr. Jack Kellam, developed a simple but effective technique for excavating and photographing striated and polished surfaces. Most of the better examples have been recorded b y colour stereographic pictures. Well in excess of 100 pavements have been recorded in the Spring Plains-Derrinal Area, including large roches moutonnees, demonstrating beyond reasonable doubt that the Ordo vician bedrock in this area has been ice carved, and that the exposures underneath and adjacent to the Permian deposits are exhumed Permian subglacial surfaces .
Remapping of the Permian boundaries by E. Wilkinson has shown that the contacts are highl y irregular, and revealed many more pavements. Several of the fault contacts shown on present geological maps do not exist , thus post Permian tectonic activity has not had a major influence on present distribution of the glac ial deposits.

A series of indurated, aragonite and Mg- carbonate sub-fossil stromatolites has been discovered in a Holocene gypsum lake (Marion Lake) on southern Yerkes Peninsula, South Australia. Similar living s tromatolitic structures occur in a nearby lake (Inneston Lake) where the processes of their formation can be studied in detail.
Marion Lake is situated near the township of Stenhouse Bay. It contains several metres of Holocene sediment overlying shelly, calcreted Pleistocene sediments.
The stratigraphic sequence reflects progressive restriction, by barrler formation, of an elongate lagoon-like embayment formed during the postglacial sealevel rise. Deepest sediments overlying the Pleistocene unit are seagrass bank facies, skeletal muddy sands with root fibres. These pass up into a 2-3 metre thick gypsum sequence comprising massive crystal gypsum overlain by sandsize gypsum crystals with ripple and cryptalgal structures. The gypsum sequence is intercalated with thin (1-2 mm) finely - laminated aragonite layers which in some areas, particularly marginal to the lake, form stromatolite heads.
The 100-200 metre wide marginal flat of Marion Lake is covered with indurated stromatolites, up to 20 cm in relief , which include laterally-linked types as well as oncolites. These have been on-lapped with carbonate sediment. In one area within the lake, stromatolite heads up to 1 metre in he i ght occur, partly buried in seed-sized gypsum sediment.
A typical stromatolite from Marion Lake (see photograph*) includes a central core of carbonate having an irregular fenestral fabric. Occasional gypsum crystals occur in this core, although it is dominantly composed of finely crystalline aragonite and Mg-calcite with a clotted texture. This core is surrounded by a zone, up to several centimetres in thickness, of finely-laminated aragonite and Mg- calcite with several light and dark laminae per millimetre.
Preliminary observations in the zone of active stromatolite growth at nearby Inneston Lake suggest that the irregular core observed in the sub- fossil stromatolites results from carbonate replacement of pre-existing gypsum "stromatolite" structures. These are densely covered with algae during their growth in Inneston Lake. It is uncertain whether the algae play an active or a passive role in moulding these gypsum structures, however the irregular fenestral fabric is produced at this stage.
This central core is ultimately covered by a growth of smooth mat , which either traps or precipitates aragonite. This grows possibly in response to a progressive change in the chemical and physical environment.
It is assumed that complete induration, by aragonite growth, occurs when the stromatolites are stranded by regressive processes During this time, the central gypsiferous core is largely replaced by aragonite and Mg-calcite, preserving its original fabric.

DEEP SEA DRILLING IN AUSTRALASIAN WATERS
The Deep Sea Drilling Project drilled 57 s i tes in the oceans of the Australasian region during 1971- 73 , and the impact of this work on geology and geophysics was discussed at the Chal l enger Centenary Symposium held 20- 22 August 1974 at Macquarie University The proceedings of the symposium have now been published Besides the abstracts of some 34 papers , this volume of 36 pages contains a bibliography of deep sea drilling in the region and an annotated map showing drilling sites and important geological and geophysical features in the region. The proceedings therefore provide a convenient reference for oceanic studies in the region. The p apers encompass the results of drilling and their impact on mode l s of the eastern Indian Ocean , the Southern Ocean , and the Southwest Pacific , the state of knowledge of studies of the deep seafloor, from pa laeomagnetism to environmental analysis , and an outline of the projected International Phase of Ocean Drilling (IPOD) The range of interests brought into focus by the DSDP and its impact on Australian and New Zealand geoscience are well brought out in this volu me.

Sir,
The recent Australian Geological Convention I feel was a great success, not only in the staging of such an event but for the chance for geologists to gather together to converse. Congratulations must go to the organising committee for the wonderful job they did.
However I was disappointed by one fact. Of the 300- odd geologists in attendance there was a great deficiency in geologists who are High School Science Teachers. The situation is even worse when one considers that the Convention was held during school holidays when teachers were free to attend.
This deficiency could be accounted for by saying the Convention was too specialised and did not contain relevant information for persons of this part of the geological spectrum. This fact I do not believe. Being a geologist who is a Science Teacher and attending the Convention , I found that the Convention did give me relevant information both for my classroom and for my own interests.
I account for the absence of Geology Teachers by their lack of professional approach to Science teaching, this being not typical of geology teachers alone. Although the bulk of the blame for this attitude lies with the geology Science Teacher him or herself, the Geological Society of Australia ought to do more to encourage the geologist who is teaching in High Schools to join the Society.
At the General Meeting of the Society , held at the Convention , it was stated that the lack of growth of the Society is poor , new members just maintaining the loss by those leaving the Societ y and death. But the Society is neglecting at least one large group of people who are suitably qualified to become members. Also if the implementation of the Society 's new rule allowing the admission of high school students to the Society as student members, is to be successful and achieve its aims we will need geologists associated with the students to tell them about the Society and nominate them for admission
I feel Geologist-High School Teachers have been neglected by the Society. Let's see a movement to provide these geologists with (a) the knowledge of the Society's existence, (b) the aims, functions and benefits of belo~ging to the Soc iety, {c) how they can join and (d) the forthcoming ne w rule prov idi ng for high school student membership.
Most of the Divisions have a Geological Training and Education sub- committee The means are already provided for an increase in this type of membership. We need to get up and do something about it and we will all reap the benefits that a larger membership will provide.

RE!-10TE CONTROL
Remote sensing for earth resources covers a range of techniques embrac ing gamma-ray spectrometry, photography in the visible and infra-red regions , radar, TB and multispectral scanning, thermal-infra-red spectrometry and other methods including sate llite imagery. These techniques are finding increasing application in various forms of mapp ing geography , geology, engineering, town planning, agriculture, forestry, hydrology, oceanography , fisheries, meteorology, environmental studies and disaster prediction.
The Australian Remote Sensing Association was formed in December 1973 and the inaugural general meeting held in June 1974 with the following aims and objectives:-
1. To bring together those progressionally engaged in remote sensing together with those who wish to l earn more about the techniques.
2 To provide a forum for free interchange of ideas and to disseminate new knowledge, news and information within Australia and from abroad
3. To promote knowledge and public awareness of the subject of remote sensing.
4. To provide a means of introduction to the subject for students and people currently unfamiliar with its applications and technology
5. To maintain close liaison with other organizations here and abroad in the immediate field of remote sensing and seek co- operation in allied fields concerned with remote sensing.
The Association has already produced its first two Quarterly Bulletins and a number of technical meetings have been held in New South Wales , Victor ia and south Australia. State branches have or are being formed in New South Wales, Victoria , A.C.T ., South Australia and Northern Territory. Details of the branches may be obtained from the Association's Secretary.

The motion picture "Earthquake" is unique in not having a gaping chasm open up to swallow a crowd of extras. True, a little crack develops on the hillside under the heroine, but this ruffles her less than the poor performance of the tie rods in the steel foundations of the house up the hill (which house falls on her). That's the way it is all through, structural effects predominate over geological ones. A few inexpensive ground effects include collapse of a trench containing an eminent seismologist during the foreshock (Quote: Farmer Gibbs: "I still don't understand what you're doing with this trench on my land"); and a brief cut to what I took to be the formation of "mole track" compression ridges en echelon to the wrench faulting, which effect appeared to be produced byuprooting a buried length of wire. Curiously for the intensities attained , there were no mud volcanoes or sand boils, although I should have welcomed the sight of A. Gardner hoist on a jet of mud as one of the great moments of the silver screen.
Structural effects were correspondingly plentiful. A column more slender than the aforesaid A. Gardner failed while clasped to her famous bosom, revealing no hoop steel and indeed no longitudinal steel either. In fact tangled "rio" was remarkable by its absence from the debris. Brick work fell and lay about in coherent panels like the cladding used to refurbish old weatherboard houses, but facing slabs fell away convincingly from tall buildings - which style of construction seems to be one of the producer's hangups. Timber houses performed well - helped by the trick of shaking the camera not the scene, but loose objects on shelves, window glass and mission bells in a belfry all did their things.
A couple of effects that were obviously wrong were that all the destruction took place without the production of dust, and electrical conductors burnt from the free end - like fuse.
The damage to the interior of the Seismological Observatory at Pasaaena was interesting. The plot development scenes (there was a plot) were certainly in the actual building, but presumably it was a mockup that was shown with its filing cabinets falling and ceilings caving in - while the Helicorder stayed on scale.
The "Sensurround" process intended to simulate earthquake shaking by provision of a separate low frequency sound track and special speakers in the auditorium did not swing the delicately suspended disbelief of this reviewer. Gut-vibrations there certainly were, and even some jerks, but all a bit theatrical. Perhaps if they had trickled some P,laster-dust into the air-conditioning.

The 'Earthquake' review brings to mind the Research report on Australian earthquakes featured in Search, Vol. 6 (No. 1-2) Jan.-Feb. 1975 which shows the location of seismograph stations and epicentres of earthquakes with magnitude greater than 4.
Is it a coincidence that there is a good correlation between the location of stations and the location of earthquakes? For those who would like more and better earthquakes there is probably a moral in this somewhere.
