Abstract

A genetic relationship is shown for the noble-metal mineralization (up to 11.3 g/t of Pt and platinoids and 2.58 g/t of Au) discovered in the Poperechnoe Fe–Mn deposit and the fluid–explosive breccias. The composition of platinoid minerals is in agreement with the characteristics of ore and placer formations of the Ural–Alaskan type and corresponds to the isoferroplatinum–osmium igneous paragenesis. The noble metals were crystallized at the conditions that should take place at the crust–mantle boundary under partial melting of the slab rocks. The near-surface occurrence of these metals is caused by the rising of high-mobile fluid flows. The data obtained testify to the expedience of searches for noble metals associated with occurrences of fluidolites.
