摘　　要：新疆若羌县东昆仑阿布拉斯南铜金多金属矿属秦岭—祁连山—昆仑山中央造山带的西延部分,大地构造单元属于塔里木—华北板块,二级构造单元属柴达木微版板块,三级构造单元属祁曼塔格古生代复合沟弧带,地层划分属于东昆仑之祁曼塔格分区;矿床产于石炭系打柴沟组中的大理岩类的矽卡岩带内,铜、金、铅、锌等主要成矿元素的矿化作用受地层及期后气水(热)液矿化作用的影响,具明显的多阶段性,形态以层状、透镜状为主,产出部位明显受地层控制,属层控热液改造型铜金矿床。Southern Ablas copper-gold polymetallic deposit in East Kunlun of Ruoqiang County belongs to Qinling-Qilian Mountain-westward extension of central orogenic belt of Kunlun. Geotectonic unit belongs to Tarim-North China plate, secondary tectonic unit belongs to the Chaidamu tiny version of the plate, the three-level tectonic unit belongs to Qimantage Paleozoic composite arc trench belt. Stratigraphic division belongs to Qimantage partition of East Kunlun. Deposits occurred in skam belt of Daeaigou formation. Mineralization of copper, gold, lead, zinc and other main ore-forming elements are affected by formation and gas-water hydrothermal mineralization. The orebody appears in bedded and lenticular shapes, belonging to the stratabound hydrothermal modified types copper-gold deposit. Output parts are controlled by the strata.
