New gold-ore occurrences in carbonaceous deposits of the Southern Urals

Resumo

This work presents brief descriptions of the geological structures of new gold-ore occurrences (Osipovskoe, Larinskoe, Amurskoe, Chernoozerskoe, and Otnurok) in carbonaceous deposits of the Southern Urals. It is shown that these occurrences are localized in intensively dislocated, silicified, and sulfidized rocks and are intruded by numerous dykes of various compositions. It was revealed that the most important gold-ore occurrences are confined to a high-grade greenschist facies zone within the frame of Beloretsk and Larino domes, which can be an important criterion for searching for gold.
