| Abstract: | Zhashui Ag-Pb polymetallic ore deposit is located in northern Qinling geosyncline. In this paper, its geological features and metallogenic background are introduced. The volcanic dynamics,physical-chemical conditions of metallogeny and ore-forming experimental simulation are discussed in detail. Based on the existence of paleovolcanic activity, the protolith characters and geochemistry of ore-bearing rock series, the authors study the law of volcanic activity in Middle Devonian period. The Physical-chemical conditions of metallogeny. including temperature, pressure, pH and Eh of mineralizing solution, are also determined. The evolution of salinity, f(O2), pH, M (H2S), M(SO2-4) (M is mole fraction of certain component ), t (temperature) and a(ionic activity)of mineralizing solution suggests that the mineralization was a long-term dynamic process. Finally, the metallogenic pattern is established. |
