Zones in the pyrite-sphalerite association of sulfide deposits Vesennee and Tash-Yar (South Ural)

Abstract

Based on the example of the Tash-Yar and Vesennee deposits, a fundamentally new approach to the problem of diffusion of elements at the boundaries of ore minerals of the pyrite-sphalerite association is considered in the article, which makes it possible to calculate the temperatures and duration of transformations of ore objects, the impact of intrusive bodies (Osennee, Avangard and many others), or experienced deep regional metamorphism (deposits of Karelia, the Baikal region, the Yenisei ridge).
