摘要(Abstract)：

香山含铜镍矿岩体位于东天山北部的土墩-图拉尔根镁铁-超镁铁岩带中段,受康古尔塔格-黄山深大断裂控制,为由辉长岩、辉橄岩、细粒辉长岩和钛铁辉长岩组成的复式岩体。香山铜镍矿床岩石铂族元素总量(∑PGE)变化范围为0.74×10-9～2.82×10-9,矿石∑PGE变化范围为20.64×10-9～148.99×10-9,PPGE(Pd、Pt)和IPGE(Ru、Ir、Os)之间分异均较弱,二者具有相似PGE原始地幔标准化配分曲线形式。香山铜镍矿床原生岩浆w(MgO)下限值为4.97%,源于亏损型地幔,PGE丰度较高,母岩浆为高镁玄武质岩浆,PGE处于亏损状态且亏损的原因是发生了硫化物熔体不混溶作用,引发硫饱和的机制为地壳物质同化混染作用,以及橄榄石、辉石和基性斜长石等矿物的结晶分离作用。

关键词(KeyWords)： 香山;铜镍矿床;PGE;硫化物熔离作用
