摘要
对黑龙江省东部五星Cu-Ni-Pt-Pd矿床的矿体和与成矿有关的镁铁质杂岩的PGE-Au以及铁族、亲铜元素的地球化学特征研究表明：它们均以亏损Cr、IPGE和富集Ni、Co、Cu、Pt和Pd（Pt〈PD）为特征，与成矿有关的镁铁质岩来自地幔部分熔融形成的玄武岩浆，岩浆（房）演化以结晶分离为主，伴随熔离作用。结合地质和岩相学特征，初步确定铜镍硫化物矿化在岩浆熔离作用的基础上产生，而铂钯矿化则主要发生在岩浆期后，以热液交代作用为主产生。因此，五星矿床是一个岩浆型铜镍硫化物和铂钯热液型复合的内生矿床。
The geochemical characteristics of platinum group element （PGE）-Au, iron group and chalcophile elements in the Wuxing Cu-Ni-Pt-Pd Ore Deposit in eastern Heilongjiang province and mineralization of the mafic complex showed that they were generally depleted Cr and IPGE and enriched in Ni ,Co,Cu,Pt and Pd（ Pt 〈 Pd） ,and the mineralization-related mafic rocks origined from the basaltic magma which formed by the mantle partial melting. The evolution of magmatic chamber was mainly crystallization separation, accompanied with liquation. Combined with geological and petrographical features, the paper determined, tentatively, that the mineralization of Cu-Ni sulphide created on the basis of magmatic liquation,while Pt-Pd mineralization occurred mostly by the hydrothermal metasomatism in post-magmatic stage. So, the Wuxing Deposit should be a composite endogenic deposit which combined with magmatic Cu-Ni sulphides deposit and Pt-Pd hydrothermal deposit.
