Bismuth-rich aurostibite: A product of maldonite replacement in a volcanogenic-plutonogenic Darasun deposit (Eastern Transbaikalia)

Under endogenous conditions aurostibite is stable at a low sulfur fugacity within the field of pyrrhotite stability. Aurostibite occurs in hydrothermal plutonogenic, volcanogenic plutonogenic, and telethermal, sometimes volcanogenic, as well as metamorphosed, deposits. Mineral aggregates of B (tourm...

Description
Summary:Under endogenous conditions aurostibite is stable at a low sulfur fugacity within the field of pyrrhotite stability. Aurostibite occurs in hydrothermal plutonogenic, volcanogenic plutonogenic, and telethermal, sometimes volcanogenic, as well as metamorphosed, deposits. Mineral aggregates of B (tourmaline) stage, Mo stage, the AuBiSbAs stage, the AsSb stage, and quartzcalcite stages are usually combined in ore bodies of the Darasun deposit.
