摘　　要：攀西-滇中地区位于上扬子地台西缘与康滇地轴的过渡区域,是西南地区重要的铅锌矿成矿区。区域内含矿层位多,由上震旦统灯影组到三叠统间地层皆有分布,SN,NE向断裂构造发育,也为区域内铅锌矿的成矿及后生改造起着重要的作用。因此大多数矿床具有典型的层控铅锌矿特征。而特定层位、构造部位、铅锌矿组合异常及碳酸盐岩化等围岩蚀变就成了区域内找矿的主要标志。The Panxi-Central Yunnan area is located in the transition region between the western margin of the Upper Yangtze Platform and the Kangdian axis, and is an important lead-zinc metallogenic area in the southwest of China. There are many ore-bearing horizons in the area. The strata from Dengying Formation of Upper Sinian to Triassic are all distributed. SN and NE trending faults are well developed. They also play an important role in the mineralization and epigenetic transformation of lead-zinc deposits in the area. Therefore, most deposits have typical characteristics of stratabound leadzinc deposits. Surrounding rock alteration, such as specific horizon, structural location, anomalous Pb-Zn ore Association and carbonate rocking, has become the main indicator of prospecting in the region.
