摘要: 颠达铅锌矿床区域上北西、北西西向断裂、褶皱十分发育.铅锌矿体呈似层状、脉状沿断层接触带产于F1断层上盘波里拉组（T3b）中厚层状泥晶灰岩中.矿石类型简单，矿体的产出受地层、构造控制较为明显.根据矿床地质特征，结合区域地质构造演化，认为本矿床是该区较为典型的碳酸盐岩层控热液脉型铅锌矿床，并建立了成矿模式.

Abstract: The Dianda Pb-Zn deposit is located in Changdu metallogenetic sub-belt of Changdu-Puer metallogenetic belt, where the regional NW- and NWW-trending faults and folds are quite developed. The Pb-Zn ore bodies occurs as stratoid and veins in the medium-thick micrite of Bolila formation(T3b) in the hanging wall of F1 fault along the contact zone. The ores, with simple types, are controlled by strata and structures obviously. According to its geology and regional tectonic evolution history, the deposit is considered as a typical stratabound hydrothermal vein type Pb-Zn deposit being hosted in carbonate rocks. The metallogenetic model of the deposit is also established.
