Abstract:

 Taking the leadzinc deposit of HuanggangGanzhuermiao Metallogenic Belt as a predicted mine, this paper systematically analyzed the relationships between geological conditions including strata and magmatic rocks, etc. and leadzinc deposits, and found out the control action and manner of geological conditions on leadzinc deposit. The leadzinc mineralization has a close relationship with the Permian in spatial distribution and content compositions. Manganese calcium pyroxene skarn and volcanic sedimentary rocks provide material for leadzinc deposit. The beneficial rocks are Yanshanian acid intrusive bodies. In the metallogenic belt, the concentrated mineralization area is the intersection of multiple parts of fractures. The differently striking faults make deposits form a NE zone and an EW row, and the deposits distribute with equal intervals. Finally, we established a comprehensive prospecting model for leadzinc deposit, which consists of geological, geochemical and mineralization information and provides the theoretical basis for predicting the leadzinc deposit within the metallogenic belt.
