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。
根據雲南省境內三江地區1∶20萬地毬化學調查資料，結閤區域地質特徵及成礦規律，對該區地毬化學特徵與礦產資源找礦潛力進行研討，重點對與銅及銅多金屬礦床有關的地毬化學特徵進行分析。本區主要成礦元素有Cu、Zn、Pb、Cd、Ag、As、Sb、Hg、Be、W、Sn、Bi等，其中銅礦相關元素Cu、Pb、Zn、Cd、Ag、As、Sb、Hg、Be等與巖漿活動和沉積熱液改造有關。以本區三類典型銅礦床模型為依據，利用GIS技術進行預測，提齣銅多金屬成礦預測區14箇，其中A類5箇，B類6箇及C類3箇，為進一步礦產勘查工作提供參攷。

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 copper-polymetallic 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.
