| Abstract: | Based on the study of fluid incluion of Baoshan Sb-Au deposit, the geochemical parameters of the deposit, such as temperature, pressure, fo2, salinity. PH, Eh and the composition of ore-forming fluid are obtained suggesting that the ore-forming fluid belongs to Ca2+-Fe2+-S2--Au-Sb-CO2 system in a weak acid to alkalic and the weak reducing enviroment. The stable isotopic study indicates that the ore-forming solution originated from the mixing of closed hot brine and rainwater and the epimagmatic volcanic hot solution had a great influence on it. [Au(HS)2]-, [Sb(HS)4]-, Na2SbS3 and Na [Au(HCO3)2] are the main migrating forms of Sb and Au. During the migrating process, these complexes disassociate and deposit to form ore deposits in the favourable structure where the pressure drops, hot solution boils, H2S, CO2 and other gases escape. |
