达拉库岸Ⅱ号镁铁-超镁铁质岩体紧邻阿尔金深大断裂南侧,大地构造位置处于塔里木板块南缘活动带之中。岩体呈岩墙状产出,主体岩性为辉石岩和辉长岩,地表露头孔雀石、铜蓝非常发育,辉石岩相中赋存有斑杂状、团块状原生硫化物。从岩体特征、深部硫化物熔离、质量平衡等综合分析,岩体形成铜镍硫化物矿床条件良好(王垚等,2012)。文章通过分析金属硫化物特征来探讨其成因并讨论
The mafic-ultramafic rock mass of No.2 Dalakurian bank is adjacent to the south side of the Altyn Deep Deep Fault and its tectonic position is in the active zone on the southern margin of the Tarim plate. The rock mass is in the shape of a rock wall. The main lithology is pyroxene rock and gabbro. The surface is covered with malachite, and the copper blue is very well developed. In the pyroxenite facies, there are mottled and massive lumps of sulfide. From the comprehensive analysis of the characteristics of the rock mass, deep sulfide melting, mass balance, etc., the copper-nickel sulfide deposit formed in the rock mass is in good condition (Wang et al., 2012). The article explores the causes of formation and discussion by analyzing the characteristics of metal sulfides
