Dr. Harry V . Warren, Emeritus Professor a t the University of British Columbia and the newest Honorary Member of A E G , Visited the Denver area in l a t e September and presented several lectures a t the U.S. Geological Survey and the Geology Department, Colorado School of Mines. His themes were Biogeochemistry in Mineral Exploration and Geochemistry in Health. Dr. Warren was a pioneer in these f ie lds of applied geochemistry and his addressess stimulated great in te res t and much discussion. His v i s i t was jointly sponsored by the Branch of Exploration Research, USGS and the Exploration Geochemistry Group, Geology Department, Colorado School of Mines.

EDITORIAL --- President Art Rose

Several years ago the Research and Education Committee under the direction of A 1 Levinson considered the question of educational programs for exploration geochemists. We did not produce a recommendation largely because of the very different organization of Universities in different parts of the world, b u t there was a degree of consensus amongst the members. My own vocation as a teacher leads me back to this question, and I would 1 i ke t o suggest some thoughts on the subject for your consideration.

Several end-member approaches to educating exploration geochemists can be dis t in- guished. I suspect a large fraction of Association members were educated as geologists, and then added the i r knowledge of geochemistry largely through " on the j o b training". Another route i s education a t the graduate level, specif ical ly as an exploration geo- chemist, a t a school l ike Imperial College. A third route i s education as a general geochemist followed by "on the job training" i n exploration. An addtitional pathway i s from chemistry t o geochemistry and exploration.

My own background i s basically as a general geochemist (route 3) preceeded by degrees in geology (route 1) and succeeded by work in exploration. All these experien- ces were valuable, b u t I think the key factor in allowing me to make a contribution to the profession was an excellent background in basic science and geochemistry. Therefore, I would l ike to promote more such background for exploration geochemists.

Specifically the following topics seem desirable in the education of future explo- ration geochemists:

1 . Basic geochemistry, including distribution of elements in isotopes, and the natural processes governing element and isotope distribution: and under- standing of aqueous geochemistry i s important.

2 . Geology , a good basic background incl udi ng mi neral ogy and crystal 1 ography , petrography and petrology , structural geology, geomorphology and surface processes, and f i e ld geology.

3. Economic geology, covering types of mineral deposits and processes forming them, as well as economic aspects.

4. Chemistry, including general qua1 i ta t ive and quantitative analysis.

5. Instrumental chemical analysis.

6. Physical Chemi s t ry , i ncl udi ng thermodynami cs and ki neti cs in order to under- stand chemical processes a t a relat ively fundamental level .

7. Physics, including mechanics, heat, optics, e l ec t r i c i ty , magnetism, nuclear, and modern aspects.

8. at he ma tics through to different ial equations and matrix algebra, t o allow an understanding of physics and physical chemistry, and the manipul a t i on of large data se ts .

9. Basic s t a t i s t i c s and probability to lay the groundwork for the s t a t i s t i c a l , . treatment of data and probabi 1 i ty in exploration pl anni ng . t )

10. Computer programming.

Newsletter No. 33 page 3

On top of these basic disciplines should be added material on general mineral exploration and geochemical and geophysical exploration; and a t the graduate level a thesis project to furnish some f i r s t hand experience in planning, chemical analysis and interpretation of data. However, I tend to go relatively l ight ly on the specifics of exploration; i f a choice has to be made I believe the applied aspects are more easi ly learnt outside the college than the basics. On the other hand a s ignif icant purpose of some of th i s applied material i s to promote an appreciation o f , and in te res t in , applications, which tend to be lacking in many U.S. University geology programs. A key factor in th is regard i s summer jobs in exploration, these furnish important experience, motivation and perspective.

Much more could be said on this topic, b u t perhaps the above i s enough to place several questions before you. Do you agree with my emphasis on the basic background ? Or i s a heavier dose of exploration desirable with a concomitant cutting of these basics ? Do employers need and want new recruits who can jump into the midst of exploration, or can they use them a t a less responsible level for a year or so while they learn applied techniques ? Or perhaps more t o the point, which type of background should the majori t.y of exploration geochemists receive since not a l l employers have the same requirements ? And f ina l ly , what can the Association do to ~romote bet ter education ? I would be interested in your comments and suggestions, e i ther direct ly t o me, or as l e t t e r s or short a r t ic les fo r publication in the Newsletter.
