摘　　要：青海省多彩地玛地区位于"三江"北段著名的有色金属及贵金属成矿带,近年来的地质矿产研究与预测取得了显著的成果。文章通过大量的野外地质调查,结合前人的研究成果,对多彩地玛铅锌、铜多金属矿床产出地质特征及找矿方向进行了总结,系统阐述了多彩地玛矿区的岩石、构造地质特征和矿体特征,分析了铅多金属矿成矿条件、矿化成因和找矿标志,为区内进一步找矿工作提供了思路。The study area is located in the northern segment of＂Sanjiang region＂in Qinghai province,which is part of the well-known Sanjiang nonferrous and precious metal mineralization belt.In recent years,with the constant development of geological work and resource assessment in the region,the situation has been largely changed.Regional geological survey not only has improved the degree of fundamental geological work,also has made a remarkable implementation of the metallogenic research and prediction.Based on a huge field geological work and previous researches,this paper summarizes the geological features and prospecting of lead,zinc and copper polymetallic deposit in Duocaidima area.Meanwhile,the systematic exposition of geological structural features and features of ore bodies in study area,as well as the analysis on metallogenic conditions,genesis,and prospecting,will provide the basis for expanding the prospecting area.
