摘　　要：根据云南省境内三江地区1∶20万地球化学调查资料,结合区域地质特征及成矿规律,对该区地球化学特征与矿产资源找矿潜力进行研讨,重点对与铜及铜多金属矿床有关的地球化学特征进行分析。本区主要成矿元素有Cu、Zn、Pb、Cd、Ag、As、Sb、Hg、Be、W、Sn、Bi等,其中铜矿相关元素Cu、Pb、Zn、Cd、Ag、As、Sb、Hg、Be等与岩浆活动和沉积热液改造有关。以本区三类典型铜矿床模型为依据,利用GIS技术进行预测,提出铜多金属成矿预测区14个,其中A类5个,B类6个及C类3个,为进一步矿产勘查工作提供参考。Based on the scale of 1 ： 200 000 regional geochemical exploration data obtained from Sanjiang region in Yunnan Province, this paper describes geochemical characteristics and the potential of mineral resources in combination with the regional geology and met- allogenic regularity, and discusses the key elements related to copper and coppcr-polymetallie deposits. The metallogenic elements in the area mainly include Cu, Zn, Pb, Cd, Ag, As, Sb, Hg, Be, W, Sn and Bi, some of which are copper-associated metal elements, such as Cu, Pb, Zn, Cd, Ag, As, Sb and Hg are related to magmatic activities and sedimentary and hydrothermal alteration. Above all, the copper target areas for exploration in near future are delineated, which include five Grade I areas, six Grade Ⅱ areas and three Grade Ⅲ areas according to the three typical copper or copper-polymetallic deposit models for filtering and evaluation by GIS technology.
