摘　　要：青海多彩当江地区位于三江多金属成矿带,具有较好的找矿前景。以该区1∶5万水系沉积物地球化学测量数据为研究对象,结合研究区内的米扎纳能铜铅锌多金属矿床的水系沉积物地球化学结构特征与地质特征进行了剖析,总结了研究区的地质地球化学找矿标志,并提出了龙格东多铜锌多金属找矿远景区,为该区的找矿工作提供了新方向。The Dangjiang area in Duocai town Qinghai province is located in the Sanjiang polymetallic ore belt thus potential for futher prospecting.This paper deals with geochemical data of river sediment survey at scale 1∶50000 in the area and geochemical and geological characteristics of Mizananeng Cu-Pb-Zn polymetallic deposit in the area are analyzed then geological-geochemical prospecting marks for the area is summerized and Cu-Zn polymetallic target at Longgerdongduo point out and a new ore prospecting direction determined.
