塔里木南缘达拉库岸铜镍矿矿物特征与成矿意义

达拉库岸岩体位于塔里木南缘活动带,喀拉米兰晚古生代沟弧系中段北侧。主要岩石类型有二辉橄榄岩、单辉橄榄岩、橄榄二辉岩、单辉辉石岩、含长辉石岩和辉长岩。矿石结构类型是星点状、斑杂状、浸染状和海绵陨铁结构;硫化物包括磁黄铁矿、黄铜矿、镍黄铁矿和黄铁矿,矿物组构特征显示出成矿过程的多阶段性,成矿时代可以划分为岩浆成矿、残余岩浆热液成矿以及表生氧化期。从岩体特征、矿石结构/构造、硫化物晶体化学特征和质量平衡等综合分析,岩体具有形成岩浆型铜镍硫化物矿床的良好条件,后期勘探应重视使用物探方法圈定岩体和矿体。...

The Dalaku＇an mafic-uhramafic intrusion is located in the north of the middle section of Late Paleozoic Karamilan arc,the southern active margin of Tafim. Its rocks consist of iherzolite,wehrlite,olivine websterite,websterite, clinopyroxenite and gabbro. The ore structure types include star-dot form,spot shape,disseminated and sideronitic textures. Sulfides comprise pyrrhotite,ehalcopyrite, pentlandite and pyrite,whi
