摘要
新疆某镍矿床矿体产于同源同期侵入的基性—超基性岩体内,其含矿岩石为橄榄岩、橄辉岩以及辉石岩,镍矿化无论从时间上和空间上都与岩体的侵位密切相关。从岩石地球化学的角度研究岩浆岩特别是超基性岩与成矿的关系,运用岩石化学各种图解分析,认为与该矿床形成密切相关的超基性岩为铁质超基性岩,具有贫铝的特点,通过分析认为该镍矿床的形成具有强的岩浆岩成矿专属性。
The studied Ni deposit distribute in the mafic-ultramafic of the same source and the same period and usually in peridotite , olivine pyroxenite and pyroxenite. Ni mineralization shows close time-spatial relationship with the mafic-ultramafic complex and formed through magmaticliquation. This paper focus on the metaUogenic specialization between the magma and the mineralization through the study of the rocks geochemistry. There are some conclusions that the multimafic is rich Fe and poor Al, the ore-forming has the character of strong metallogenic specialization.
