摘要
新疆若羌红石山镍矿产于早二叠世镁质基性-超基性岩中,杂岩体由多种岩相组成,成矿主要与橄榄岩相关系密切.蚀变类型主要有蛇纹石化、滑石化、伊丁石化、纤闪石化、绿泥石化等,含矿岩体具高磁、低重力、低阻及较高极化率异常特征,Cu,Ni,Co,Cr,Zn等元素显示较突出异常,地表存在次生镍矿风化壳.矿床成因属岩浆晚期就地熔离型镍矿.
Xinjiang Ruoqiang Hongshishan nickel is located in the active foreland of Talimu plate—west Beishan paleozoic rift,whichi is one of the most exquisite structure magma belts in Talimu igneous rocks Province.There are many mafic-ultramafic intrusions associated with magmatic Cu-Ni deposits such as Poshi、 Poyi、Luodong,are located along the belt,and Hongshishan nickel deposit is just distributes in the Mid-Permian mantle source basic-ultrabasic rocks.Hongshishan nickel deposit is a large-scale deposit formed mainly by magma in-situ liquation,combined with permeating.
