摘    要：老厂银铅矿床主要受断裂构造控制.对矿区地层元素丰度、稀土元素、稳定同位素及围岩蚀变等进行研究,结果表明,成矿物质有幔、壳两大来源,矿床具多期多成因的特征,属幔－壳型多因复成矿床.

Abstract: Laochang Ag-Pb ore deposit is mainly controlled by faults. According to the research of strata element contents, REE, stable isotope and wall rock alterations, ore-forming substances are from both mantle and crust, and the ore deposit has the characteristics of mutiple metallogenesis and polygenetics, belonging to mantle-crust polygenetic compound deposit.
