摘要
The Zhaxikang Pb-Zn-Sb polymetallic deposit,which is located in the south Tibetan detachment system, is one of the few large Pb-Zn-Sb-Ag symbiotic deposits in Tibet that characterized by great variety of sulfosalt minerals. The deposit occurs in Lower Jurassic Ridang Formation, with the rocks being carbon-bearing calcareous slate,calcareous slate,sericite slate, shale and quartz sandstone. The ore bodies in Zhaxikang deposit are mainly controlled by SN and NE-SW striking tensional faults. The immiscibility which was marked by the escape of gases from the fluid occurred during the mineralization, whereas this immiscibility resulted in sulfide mineralization. The genesis of this deposit belongs to medium-low temperature hydrothermal type formed during groundwater convection cycle driven by sedimentary-structural-geothermal activity.
