摘　　要：沙泉子地区处于东天山东部,其大地构造属于塔里木盆地北缘,觉罗塔格晚古生代岛弧带,区域构造格架以NEE—SWW向构造为主体,控制着本区各地层单元的展布。区内硅化破碎蚀变带型、石英脉型铜金矿化、铜金银矿化和金银矿化发育,金银矿受NEE向硅化破碎蚀变带控制,相关的矿化蚀变主要有硅化、铅锌矿化、黄铁矿化、碳酸盐化等。通过探槽及少量的钻探揭露,粗略查明了金银矿化的分布、规模、品位变化及控矿因素。Shaquanzi area is located in the eastern of the East Tianshan,the tectonic location is belonged to the north margin of Tarim Basin,Jueluotage island-arc belt of Late Palaeozoic.The main regional structure framework is in NEE-SWW,which controls the distribution of each stratigraphic unit in this area.Cu-Au,Cu-Au-Ag and Au-Ag mineralization of fractured silication alteration zone type and quartz vein type are developed in the area,Au-Ag deposits are controlled by NEE fractured silication alteration zone.The related alterations are mainly silication,Pb-Zn mineralization,pyritization and carbonatation.With some trenches and drilling holes,the distribution,scale and grade variation and the controlling factors of Au-Ag mineralization are ascertained as well.
