Geological Characteristics of Devonian Sandstonetype Copper Deposit in Kusilafu Area,Southwestern Tarim Basin:Evidence from Saigeziganleke Copper deposit

  • 摘要: 塔里木盆地西南缘库斯拉甫一带砂岩型铜矿发育于晚古生代早期大陆边缘裂陷盆地中,含矿岩系为一套滨海-滨浅海相碎屑岩+碳酸盐岩建造,矿体主要赋存于泥盆系“浅-紫”交互带的浅色砂岩中,受一定层位制约,具有沉积矿床的一些特征。含矿岩系的微量元素和稀土元素特征显示出矿区西侧前寒武纪结晶基底可能为铜矿的初始富集提供了物质来源。沿构造带(线)矿体明显发育碳酸盐化和硅化等围岩蚀变,矿区附近的早石炭世中基性岩浆喷发活动可能对矿源层具有改造和富集作用,成因上总体表现为沉积改造型矿床的特征。在相似层位中普遍发育铜矿化,表明这一地区具有形成中-大型砂岩型铜矿的资源潜力。
    Abstract: In Kusilafu area, southwestern Tarim Basin, the sandstone-type copper deposit was developed in the rift basin of late Paleozoic's early period continental margin.Ore-bearing rocks are coastal-shallow coastal clastic + carbonate constructions.Ore body occurs in the light-colored clastic rocks of Devonian light-purple interlayer, which was constrained by certain layer, with the geological characteristics of sedimentary deposit.The trace and rare earth elements of ore-bearing rocks show that, the Precambrian crystalline basement in the west side of this deposit may provide some material source for the initial concentration of this copper deposit.The ore body was occurred wall rock alterations (such as carbonization and siliconization) along the tectonic zone (line).And the source layer of this deposit might be transformed and enriched by the Early Carboniferous intermediate-basic volcanic magmatic activities, thus this deposit performs the characteristics of sedimentation-hydrothermal reworked deposit.And the copper mineralization was developed in the similar layer, showing a potential of forming middle-large sandstone-type copper deposit in this region.
