摘　　要：通过对青海省都兰县加羊铅锌银多金属矿矿床特征和矿体特征进行分析,尤其对矿区内出露地层有奥陶系滩间山群内构造的综合研究,推断矿床为热液交代(充填)型铅锌银矿床,成矿期为燕山晚期。矿区内矿体分为东西两个矿区群,受区内奥陶系滩间山群的褶皱构造、断裂构造控制,通过系统总结本区的地球物理特征、地质特征、矿化体特征,建立本区成矿模型,为本区同类型铅锌银多金属矿矿床找矿具有重要意义。Based on the analysis of the deposit characteristics and deposit bodycharacteristics of Jiayang Pb-Zn-Ag polymetallic deposit in Dulan County,Qinghai Province,especially the comprehensive study of the structure in the Ordovician Tanjianshan Group in the exposed strata in the mine area,it is inferred that the deposit is a hydrothermal metasomatic(filling)type Pb-Zn-Ag polymetallic deposit,and the mineralization period is the late Yanshan period.The deposit bodies in the mining area are divided into two mining areas,east and west.They are controlled by the fold and fault structures of the Ordovician Tanjianshan Group in the area.By systematically summarizing the geophysical,geological,and mineralization characteristics of the area,a mineralization model is established,which is of great significance for the exploration of similar lead-zinc silver polymetallic deposits in the area.
