摘要
云南省兰坪县华昌山铅锌银铜矿,矿体呈似层状、透镜状,主要赋存于华昌山逆冲断裂的次级断裂破碎带中,构造控矿明显.近矿围岩、容矿岩石为上三叠统三合洞组(T3s)白云质灰岩和骨屑灰岩.该铅锌银矿体赋存特征、矿石组合、矿石组构和围岩蚀变特点与密西西比型(MTV)铅锌矿床较为相似.
The orebody of Huachangshan Pb-Zn-Ag-Cu deposit in Lanping,Yunnan is stratoid,lanticular mainly in the secondary fault fracture zone of Huachangshan thrust,ore control of structure clear.The wall rock near orebody,ore-bearing rock are Upper Triassic Sanhedong Formation(T3s) dolomitic limestone and bone-clastic limestone.The Pb-Zn-Ag orebody occurrence feature,ore composition,ore fabric and wal rock alteration are similar to those of Mississippi-type deposit(MTV).
