Geochemical zonality of skarn-gold deposites of the Western Siberia

Abstract

Geochemical zonality of Western Siberia gold-skarn deposits has been investigated. Concentric zonal construction of geochemical fields' anomalous structure accompanying studied deposits has been revealed. Groups of concentrating and deconcentrating (in relation to golden-ore bodies) elements have been defined. Close spatial relation between gold and chalcophile satellite elements complex, set of which can vary depending on evolution degree of hydrothermal system, has been established. The set of deconcentrating elements, accumulated on periphery of ore bodies is standard in general and includes Ni, Co, Cr, V, Ba, Mn. In the first part of the article the geochemical zonality of the Sinychinskiy type deposits has been examined, the second is devoted to zonality of the Kazsk ore field and discussion of the results.
