FLUID-EXPLOSIVE BRECCIAS OF THE VORONTSOVSKOE GOLD DEPOSIT (THE NORTH URALS)
The paper analyses geological position of the Vorontsovskoe gold deposit which is untypical for the Urals folded belt. This deposit is a part of the ore-magmatic system formed in connection with the Auerbakhovsky massif at the North Urals. There are displayed data on mineralogical-geochemical and petrographic characteristics of studied gold-bearing breccias with detail description of their cement. It contains realgar and orpiment, and, in subordinate quantity, Hg-bearing sphalerite, dimorphite, routhierite and minerals of the gruzdevite-aktashite isomorphous series. Obtained data allow to attribute these gold-bearing breccias, with realgar-orpiment cement, to fluid-explosive formations. This is one of numerous evidences to consider ore deposits connected with Auerbakhovsky massif as parts of a uniform ore-magmatic system with distinct lateral zoning.
