A Model of Supergene Transport and Concentrating of Heavy Metals
Yu. A. Kalinin, N. A. Roslyakov
Abstract
The conditions, forms and mechanisms of migration and accumulation of metals of the region of sorption-infiltration accumulation during the formation of chemically decayed residual soil, which is widespread in the south of West Siberia. The model of super gene transport and concentrating is based on the behaviour of gold, which is relatively inert metal, in the kaolinite residual soil profile with intensive karst development. Regular changes in the form of metal migration depending on physicochemical conditions and the role of specific geochemical barriers in metal concentrating are demonstrated.
