GENETIC GEOLOGICAL MODEL OF STRATIFORM LEAD-ZINC MINERALIZATION (MVT TYPE) IN EPIPLATFORM EARLY PALEOZOIC COMPLEXES OF THE SIBERIAN PLATFORM EXEMPLIFIED BY THE SINSK-BOTOMA AREA

The article discusses the issues of localization and regional features of stratiform lead-zinc mineralization in carbonate strata within the poorly studied part of the Vendian-Early Paleozoic carbonate basin of the Siberian Platform cover. It gives the characteristics of rock and material complexes, tectonic structures, facies heterogeneities in the areal stru­cture that control the position of mineralization, its morphostructural, mineralogical and geochemical features, geophysical and isotopic geochemical characteristics. It substantiates that mineralization belongs to the Mississippian commercial geological type of stratiform lead-zinc deposits, a unique feature of which within the Siberian Platform is the association of mineralization with the Devonian-Carboniferous intracontinental rifting and Pb, Zn, Ag, Mn orientation of ores. The proposed model elements make it possible to use them as pros­pecting criteria and indicators of stratiform lead-zinc mineralization, including in buried areas.
