摘　　要：华昌山铅锌矿床位于三江成矿带兰坪—思茅盆地北部兰坪矿化集中区内,赋矿围岩为上三叠统三合洞组灰岩,矿体呈似层状、脉状及透镜状,矿体主要受层位和张扭性断层的控制,矿床属喷流沉积之后经受热液叠加改造形成。近几年随着探矿工作的不断深入,在矿区普遍发现银矿(化)体,这为该区矿床的勘查提供了新的线索和思路。The Huachangshan Pb -Zn deposit is located in the Lanping mineralization concentration area of the Sanjiang metal- logenetic belt, northern part of the Langping - Simao basin. The ore - hosting rock is the Sanhedong Group limestone of Upper Triassic. The pbzinc orebodies are mostly controlled by strataform and tensile faults and occur in bed -like and lenticular shapes. The lead - zinc deposit formed by the seafloor exhalative deposition overprinted by the hydrothermal process. With the prospecting progress in the area recent years, extensive silver mineralization was found, which it provides the new clue for further exploration to find new deposits.
