MEETING OF COUNCIL MEMBERSAT NOVOSIBIRK

Several council members and members of IAGC working groups who were at Novosibirsk for the INA meeting in September 1978 to met to discuss IAGC matters. Attending the meeting were Vice Presidents Goni and Pacal and council members Coombs and Ryabchikov. Also present were L.V. Tauson, chairman of the Working Group on Geochemical Prospecting, F. Mrna, Secretary of the Working Group on Laterites, V.L. Barsukov, General Director of the Vernadsky Institute of Geochemistry, B.M. Shmakin, member of the Working Group on Geochemical Prospecting, and L.N. Kogarko, leader of the Laboratory for Physical Chemistry of Magmatic Rocks at the Vernadsky Institute. Topics discussed included the Geochemical Prospecting Symposium in Ostrava, public ation of IAGC monographs in geochemistry, status of working groups, and nominations.

GEODYNANIG5 PROBLEMS — OUTLOOKTO THE 80’s

The International Geodynamics Project comes to an end this year. Plans for a new multidisciplinary international research project to follow and build on the results of this project are well underway and were the subject of much discussion at a recent symposium called “Geodynamics Problems — Outlook to the 80’s” held in Zurich last February. It was organized by Prof. R. Trumpy (President) and W.W. Hutchison (Secretary—General) of the International Union of Geological Sciences, and immediately preceded the annual IUGS council meeting. A draft report of the IUGS/IUGG joint committee (the Kisslinger—Illies report — “The Lithosphere: Frontier for the 1980’s”) on the goals of the new international project, plus a number of invited lectures surveying many aspects of earth sciences, provided a focus for the discussions. IAGC members attending the meeting included Secretary G. M. Anderson, who gave one of the lectures, Prof. M. Griinenfelder (ETH, Zurich) and Prof. H. Winke (Max Plank Institut, Mainz).

The revised Kisslinger—Illies report has now been accepted by the IUGS executive as a basis for an international program in solid earth sciences for the 1980’s. It will be considered by IUGG at their meeting in Sydney Australia in December 1979, and it is hoped that the program will be ready for initiation at the International Geological Congress in Paris in 1980. inadvertently year, as this, from

It is a sad duty to report that the eminent Soviet geochemist, Professor V.V. Scherbina, died on July 29, 1978. Professor Scherbina served as Vice President of IAGC for four years, and spent a lifetime serving the science of geochemistry.

MEETING OF “LATERITES” WORKING GROUP

The IAGC Working Group on Laterites and Laterization and IGCP project No. 129 held a joint meeting on “Laterites and Laterization Phenomena” at Salvador (Bahia) in Brasil, Nov. 23 to Dec. 4, 1978, and a comprehensive report has been submitted by Vice President Goni. Participants at the meeting were:

This meeting continued the discussions begun at the meeting at Ouagadougou (Upper Volta), Dec. 18—22, 1977. Support from UNESCO and the cooperation of Brazilian Universities is gratefully acknowledged. —8—

The principal objectives of the working group are:

— critical evaluation of existing data in the countries concerned

— choice of research areas

— construction of a geological map of tropical alteration facies

— petrographic,geochemical, and mineralogical studies of laterite profiles

— determination of the evolution of major and trace elements in a laterite profile

— laboratory simulation

— training of local technicians

At the Salvador meeting, the following topics were discussed: (1) Concept and definition of laterites (2) A program of study of laterites in Brazil to complement the study in Upper Volta

This will include the study of the development of the oxide mineralogy and supergene alteration of a sulfide ore body in a tropical climate, and the study of one or two complete laterite profiles, complementing the study in Upper Volta.

The sulfide study will be carried out with the cooperation of the personnel at the Boquira mine (Bahia) and the Brazilian Universities. (3) Contributions of each country to the international project (4) Plans for the Congress on laterites in India (5) A geological field trip was conducted to the “Chapada Diamantina” region of central Bahia to define target areas for geochemical research.

The next meeting of the working group will be held in India at the International Congress on Laterites at the end of this year. —9—

ANNOUNCEMENT

3rd International Szjnrposiwn on Water-Rock Interaction

The International Association of Geochemistry and Cosmochemistry and the Alberta Research Council will be sponsoring the 3rd International Symposium on Water—Rock Interaction in Edmonton, Alberta, Canada, July 14 to 24, 1980. Both pre—session and post—session field trips are planned. To receive the first circular, enquiries should be directed to: Dr. Brian flitchon Secretary—General, WRI—3 Alberta Research Council 11315 — 87th Avenue Edmonton, Alberta Canada T6G 2C2

REGIONAL GEOCHEMICALATLASES OF THE UK

Produced on a scale of 1:250,000, the atlases are designed to provide systematic data on trace element levels in stream sediments as a basis for metalliferous mineral exploration, fundamental studies of crustal evolution and ore forming processes, medical geography, agriculture, pollution and environmental studies. The first atlases to be published will be of Shetland, Orkney, Caithness/South Orkney and Sutherland with the aim of extending the series to cover the United Kingdom.

Prepared by NERC’s Institute of Geological Sciences and Experimental Cartography Unit, the Regional Geochemical Atlas series is sponsored by the Department of Industry’s Chemicals and Minerals Requirements Board. The first four Regional Geochemical Atlases contain separate maps for 16 chemical elements using line symbols proportional to concentration at each sampling point. All later atlases in the series contain maps for up to 30 elements. Also included, where available, are data on occurrences of metalliferous mineralisation, relief, land use and vegetation. The geochemical, geological and topographical data are stored in digital form and the maps have been plotted using automated cartographic methods.

The Regional Geochemical Atlas series is part of the Department of Industry’s wider Regional Geochemical Reconnaissance Programme under contract to the Natural Environment Research Council. This programme includes the IGS National Geochemical Data Bank which holds data compiled in the production of the geochemical atlases, as well as regional geochemical data from other sources.

The atlases can be obtained from the Bookshop, Institute of Geological Sciences, Exhibition Road, London 5W7 2DE, Tel: 01 589 3434.

Social Program

Since the Congress is taking place in Paris the organizers will be able to plan a very attractive program for the participants and a special program for persons accompanying them.

State of Advancement of Congress Preparation

80,000 copies of the first circular were sent out in October 1977. By 1 December 1978 the Organization Committee had received 5,800 answers from 114 different countries and 4,000 persons had asked to take part in the excursions. The second circular is now available and contains the final registration form. Those interested in participating in the Congress and wishing to receive the second circular should request it from the: Secrtariat Gnral du 26me Congrs Gologique International Maison de la Gologie 77—79, rue Claude Bernard 75005 PARIS — FRANCE

IAGC Symposium

Plans are well advanced for Section 10.2.1 at ICC, which will be a symposium on Crust—Mantle Interaction. Joint organizers are C. Allegre (France) and IAGC President C. Wetherill (US).

PUBLICATIONS OF INTEREST colloguiwn on the mineralogy, geochemistry and geology of lateritic nickel bearing minerals and ores

On the occasion of the 100th anniversary of the French Society of Mineralogy and Cristallography, the National geological service (BRGM) and the Ecole nationale suprieure of geology of Nancy organized for the 17th and 18th July 1988 at Orleans (France), a colloquium on the lateritic nickel—bearing materials. The subjects dealt with concerned the mineralogy, geochemistry and geology of lateritic nickel—bearing minerals and ores with the exclusion of the mineralurgy and metallurgy of nickel.

A report containing the proceedings of this colloquium has now been published as Report No. 1 of the IAGC Working Group on Laterites and Laterization and as a report of Project No. 129 of IGCP. It contains twelve articles and 156 pages. Copies are available (42.80 FF + 6 FF postage + handling). Ask for Bulletin du BRGM, Section II No. 3, 1978.
