摘　　要：会理鹿厂－大钢厂银铜矿的矿石矿物主要由辉铜矿、蓝辉铜矿、斑铜矿、硫铜银矿、硒铜银矿及硫硒铜银矿组成，且与胶结物方解石密切共生；矿石主要是结晶粒状与交代溶蚀结构，浸染状构造。该矿床为典型的沉积成岩成因砂岩砾岩型银铜矿。Ore minerals of Luchang-Datongchang Ag-Cu ores include chalcocite, digenite, bornite,stromeyerite and eucairite which are associated with calcite as a cement.The ores have crystallinegranular and metasomatic textures and disseminated structure. The deposit is a typical sedimentary-diagenetic silver-copper sandstone.
