内蒙古阿拉善右旗开热牛都地区铜多金属矿地质特征及找矿标志

Geological characteristics and prospecting criteria of copper polymetallic deposits in Kaire Niudu area, Alashan Right Banner, Inner Mongolia

内蒙古阿拉善右旗开热牛都地区铜多金属矿,为内蒙古自治区阿拉善盟包尔陶勒盖等四幅1:5万区域矿产地质调查项目新发现矿点,铜、金矿化体主要赋存于早二叠世中细粒二长花岗岩与新太古界东五分子岩组大理岩的接触带上。本文对该区区域地质背景和矿区地质特征进行了较详细的阐述,对其找矿标志进行简要分析,为该区寻找接触交代型铜多金属矿的地质勘查借鉴和指导意义。

The copper polymetallic deposit in Kaire Niudu area,Alashan Youqi,Inner Mongolia,is a newly discovered deposit in four 1:50,000 regional mineral geological survey projects in Baoertaolegai,Alashan League,Inner Mongolia Autonomous Region.Copper and gold mineralizations mainly occur in the junction of early Permian medium-fine-grained monzonitic granite and Neo Archean marble of the East Pentamolecule Formation.Contact belt.In this paper,the regional geological background and geological characteristics of the mining area are elaborated in detail,and the prospecting criteria are briefly analyzed,which can be used for reference and guiding significance for geological exploration of contact metasomatic copper polymetallic deposits in this area.
