Biogeochemical Exploration for Mineral Deposits
Aleksandr Leonidovich Kovalevsky
VSP, 1987 - Science - 224 pages
This work is a translation of the revised and considerably supplemented edition of A.L. Kovalevsky's well-known monograph on biogeochemical methods of prospecting for minerals. The approach is essentially practical. Principles of the formation of biogeochemical haloes for 14 elements are discussed and practical results of biogeochemiacl prospecting for molybdenum and sulphide deposits are presented. An excellent chapter on methodology tells exactly how to undertake the tasks in view, including sample preparation and analysis, interpretation of data and the combination of biogeochemical techniques with other procedures. Perhaps the most important contribution made by this book is the principle of selection of suitable biosamples whose elemental content is proportional to that of the substrate. This book will be of immeasurable assistance to the practical field worker engaged in biogeochemical prospecting. It will also be of interest to geologists, geochemists, geophysicists and specialists in related areas in both academic and industrial spheres.
