Abstract
New data are presented on character of segregations and compositions of bournonite-seligmannite series minerals in gold-bearing veinlets of the Berezitovoe deposit located in the east part of the Mongol-Okhotsk orogenic belt. It was revealed that these minerals represent a discret series of stoichiometric solid compounds with formula coefficients of As in their composition varying from 0.2 to 1.2. It is shown that minerals of this series are characteristic for strongly metamorphosed ore deposits, where they are formed due to sulfide melting of initial ores under high P-T-conditions.
Key words: minerals, bournonite-seligmannite series, gold mineralization, metamorphism ore, Berezitovoe deposit, the Upper Amur region.
