Abstract:

采用ICP-MS方法分析了煎茶岭和金川硫化镍矿床岩石、矿石的铂族元素含量,煎茶岭岩体蛇纹岩的Cu/Pd比值低于原生地幔岩浆,说明岩浆熔离作用较弱,矿石的Pd/Ir比值较小,指示其多数矿石属于岩浆型,以岩浆成矿作用为主;而金川岩体的平均Cu/Pd比值远大于原生地幔岩浆,表明岩浆熔离作用强,矿石的Pd/Ir比值较大,体现了钯族元素矿化及成矿物质以幔源为主的特征。煎茶岭在成矿过程中有壳源物质的混染,整体上岩石、矿石铂族元素含量较低,这与岩浆熔离作用弱、铂族元素成矿作用不发育等因素有关;金川在成岩成矿过程中也有少量地壳物质的混染,但岩石、矿石铂族元素含量较高,反映了以岩浆深部熔离成矿作用为主的特征。
