| 摘 要： | 红旗岭铜镍硫化物矿床产于幔源超镁铁质杂岩体中，杂岩体分为含矿与非含矿两种岩石类型。工业矿床多产于富含斜方辉石的岩石中。矿化强度与蚀变强度正相关。岩石化学与地球化学表明，含矿岩体的Na、K、Al、Ca、Fe等组分明显地高于平均地幔岩组分。含矿岩体是同化了壳源组分组经历了充分的岩浆重力分异作用后脉动式侵拉的。壳源组分的加入是促进岩浆熔离作用的重要因素。

| Abstract: | The Hongqiling Cu Ni sulfide deposit occurs in mantle derived ultramafic complexes that could be divided into two types: ore bearing and ore free. The industrial ore bodies are mainly found in ultramafic rocks rich in orthorhombic pyroxene. The intensity of mineralization is positively related to the intensity of alteration of the intrustions. Evidence from geochemistry and petro chemistry indicates that the contents of Na,K,Al,Ca and Fe in ore bearing intrusions are apparently higher than those of the corresponding components in pyrolite averaged. It seems quite probable that the ore bearing intrusions were formed by repeated intruding after assimilating crustal materials penetrated and after sufficient gravitational differentiation. The addition of the crustal materials into the magma played an important role in promoting the liquation processes. |
