| 摘 要： | 华北陆块北缘是中国铜镍（铂）硫化物矿床的重要成矿区带之一。近年来，在位于该成矿带的内蒙古中部先后发现多处铜镍矿床（点），空间上构成一条重要的镁铁质-超镁铁质岩成矿带。为了探讨该镁铁质-超镁铁质岩带内额布图、温更、克布、黄花滩及小南山等赋矿岩体的成矿潜力，笔者通过搜集和研究国内外典型铜镍硫化物矿床数据，建立有利成矿信息评价指标，并指导评价本区岩体的成矿潜力。研究认为，额布图、温更和克布岩体从矿物和岩石地球化学及岩浆分异演化等方面分析，具有较好的成矿地质条件，指示较好的成矿潜力；而黄花滩、小南山岩体从目前地球化学资料分析，成矿潜力相对较弱。

| Abstract: | The northern margin of North China Craton is an important metallogenic belts of Cu,Ni(Pt)sulfide deposits.Recently many Cu-Ni deposits(or ore occurrences)have been discovered in central Inner Mongolia spreading as a mafic-ultramafic belt.In order to explore the metallogenic potentiality in Erbutu,Wengeng,Kebu,Huanghuatan and Xiaonanshan in the belt,this paper summarized and analyzed the data of the typical Cu-Ni ore-bearing intrusions.It is suggested that ore-bearing intrusions in Erbutu,Wengeng and Kebu have good geological ore-forming conditions in aspects of the mineral,the petrology and the magmatic differentiation,indicating preferable metallogenic potentiality.Whereas ore-bearing intrusions in Huanghuatan and Xiaonanshan do not show much metallogenic potentiality. |
