摘要
描述了东疆雅西KB-7化探异常特征、雅西371-西北坡(金)铜矿化带发现过程与特征,认为东疆地区下石炭统雅满苏组(C1y)中的Cu-Zn-Ag-Pb异常是寻找热水沉积型和岛弧带次火山岩型铜矿重要的新找矿方向。
The discoveries and natures of KB-7 geochemical anomaly and 371-Xibeipo gold-copper mineralized zone in the Yaxi area of eastern Xinjiang are reported in this paper. Cu-Zn-Ag-Pb geochemical anomalies, located in the Yamansu Formation of low Carboniferous age in eastern Xinjiang, are proposed to be the signs of hydrothermal sedimentary-type copper deposits and subvolcanic- to volcanic-type copper deposits in the volcanic arc belt. Those show very important new orientations for copper-finding in the research area.
