摘　　要：白牛厂银矿是近年发现探明的一大型银锡铅锌矿床。矿床产于隐伏花岗岩体外接触带的层间破碎带中，矿床围岩为中寒武纪的碎屑岩和碳酸盐岩。银主要呈硫盐矿物出现，共有２８种，常见银矿物有银黝铜矿、黝锑银矿、深红银矿、辉锑银矿等。The Bainiuchang Ag deposit is a large Ag-Sn-pb-Zn depo-sit discovered and explored in recent years. It is occurred in the fracture belt between rock beds in external contact zone of the blind granite body. The wall rock of the deposit is middle ∈ clastic rocks and carbonate rocks. Ag is mostly occurred as sulfate minerals of 28 kinds. The common Ag minerals are freibergite , pyrargyrite , miargyrite, etc.
