吉林省茶尖矿区镁铁-超镁铁质岩体地质特征及找矿方向

    GEOLOGIC CHARACTERISTICS AND PROSPECTING GUIDE OF THE MAFICULTRAMAFIC INTRUSIVE BODIES IN CHAJIAN ORE DISTRICT, JILIN PROVINCE

    • 摘要: 红旗岭铜镍矿田由红旗岭岩体群、三道岗岩体群及茶尖岩体群构成,蕴藏着大、中、小型铜镍矿床.茶尖矿区是红旗岭铜镍矿田重要组成部分,已往勘查中发现20余个镁铁-超镁铁质岩体,并在1号、新6号、9号、18号岩体中发现小型铜镍矿床,2号、10号、14号等岩体中发现铜镍矿化.从岩体特征等方面进行分析与红旗岭区对比,确定了该区的找矿标志和找矿方向,力求在茶尖矿区发现中型以上的铜镍矿床.

       

      Abstract: The Chajian ore district is an impotent component part of the Hongqiling copper-nickel orefield in Jilin Province, where numerous Cu-Ni deposits occur in different scales. More than 20 mafic-ultramafic intrusive bodies are found in the Chajian area during exploration. Among them, small Cu-Ni deposits are discovered in No. 1, No. N6, No. 9 and No. 18 rock bodies. Cu-Ni mineralization is found in Nos. 2, 10 and 14 rock bodies. Based on the characteristics of the rock bodies, with comparison to the rest areas of Hongqiling orefield, the prospecting criteria and direction are determined. It is hopeful to find middle or large sized copper-nickel deposits in Chajian ore district.
