中文摘要:
      新疆乌恰县吾合沙鲁砂岩型铜矿床位于塔西南坳陷内乌恰中新生代前陆盆地北缘,矿体赋存于新近系克孜洛依组(N1k)与安居安组(N1a)之中,圈定含矿层7条,铜矿体28条,Cu平均品位为1.12%~2.03%,矿床规模中型。含矿层呈近东西向带状展布,长7~13 km,视厚度30~180 m,产状与矿区地层基本一致,倾向330°~15°,倾角15°~40°。主要矿石矿物为孔雀石,其次为辉铜矿、铜蓝,少量硅孔雀石、自然铜等;脉石矿物主要为石英,其他有方解石、绢云母等矿物。笔者系统研究了该矿床地质特征,总结控矿因素,并确定找矿标志,分析了矿床成因,认为吾合沙鲁铜矿为受氧化-还原障控制的砂岩型铜矿,后期受到轻微改造。该矿床的发现对总结区域成矿规律,指导区域找矿和成矿预测均具有一定的指示意义。
英文摘要:
      The Wuheshalu sandstone copper deposit is located in the northern margin of Meso-Cenozoic foreland basin, southwest of the Tarim depression in Wuqia County, XinJiang. The orebody is hosted in Neogene of the Keziluoyi Formation and Anju Formation. There are 7 ore-bearing layers and 28 copper orebodies with the average Cu grade between 1.12 and 2.03% and the medium scale deposit. The ore-bearing layers are 7-13 km long and 30-180 m of apparent thickness, with a nearly zonal distribution in the EW direction and a dip angle of 15°-330°, 15°-40°. The ore minerals are mainly malachite, chalcocite, copper blue, and a small amount of silicon malachite and natural copper, etc. The gangue minerals are mainly quartz and other minerals of calcite and sericite, etc. This paper systematically studied the geological characteristics of this deposit, summarized the ore controlling factors and the prospecting indicators and analyzed the genesis of the ore deposit. it is held that Wuheshalu is a sandstone copper deposit controlled by redox barrier and some lightly tectonic activities in later stage. The discovery of this deposit is of indicative significance for the regional ore prospecting and metallogenic prediction.
