| Abstract: | There is currently widespread interest in the exploration community worldwide in the development of methods to locate deeply buried mineralisation. In the application of geochemical methods, some success has been achieved using the selective extraction of mobile and weakly bonded forms of elements (MWBE) in overburden. Studies in Russia commenced in the 1960s, and have continued in Russia and in other countries to the present time. This paper presents some examples of experimental and applied research carried out in Russia, specifically by members of VITR and then VIRG NPO Rudgeofizika (St. Petersburg). In particular, some characteristics of MWBE anomalies and rates of MWBE migration are illustrated, with reference to several case studies in geochemical exploration for base metal and precious metal deposits. |
