摘　　要：西藏申扎县下你弄巴铅锌矿床位于念青唐古拉弧背断隆系,隆格尔-冷青拉断隆;矿区主要出露第三系上新统乌郁群(N2wy)地层,其中,新统乌郁群一段安山岩为赋矿岩层;矿区内发育一系列断裂构造,属导矿、容矿构造。结合矿区地质特征、矿体特征及矿石特征研究,分析了下你弄巴铅锌矿床的类型和成矿作用,初步认为该矿床属脉状-破碎蚀变型矿床。Xianinongba Pb-Zn deposit in shenzha,Tibet is located in Nyenchen tanglha Arc-back and Longgeer- lengqingla Fault-Uplift. The main exposure stratum in the diggings is the Wu Yu group of the Tertiary Pliocene （N2wy）,the first segment of which is the ore-bearing rock.There are series of faults in the diggings, as mineral transfer, mineral deposition. Combining with the studies of the geological characteristics, ore body characteristics and ore features ,and analyzeing the deposit types and mineralization, Xia ninongba Pb-Zn deposit is judged to be a vein-fracture altered rock type.
