摘　　要：矿床大地构造位置位于兰坪-思茅盆地中北部坳陷北侧的收敛部位,成矿条件优越,是三江成矿带兰坪矿集区的代表矿床。矿床含矿岩性为上三叠统钟山组灰岩,矿体(化)呈似层状、透镜状产出,严格受控于地层层位和断裂构造的控制,发育强烈的天青石化,与黄铁矿化、石膏共生,为典型的陆相沉积-热卤水改造型矿床。The deposit is located in the convergentzoneon the north side of the north central depression of the Lanping-Simao basin.It is a representative deposit of the Lanping ore concentration area in the Sanjiang metallogenic belt,with superior mineralization conditions.The ore-bearing rock is the Upper Triassic Zhongshan Formation limestone.The ore bodies(mineralization)occur in layered or lenticular,strictly controlled by stratigraphic layers and fault structures.The alteration of celestite is intensely developed,coexisting with pyrite and gypsum.The deposit is a typical continental sedimentary-hot brine reformed deposit.
