Abstract
This paper mainly introduced the characteristics of geology and geochemistry of the silver polymetallic deposit of the Dongzigou.The genesis of deposit was discussed on the basis of mineral compositions stable isotopic geochemistry,compositions of liquid inclusions and mineralization chronology.The mineralization of deposit was related to the volcanic activity in the middle Proterozoic and the deposit is an epithermal one.
