| 摘 要： | 内蒙古查干哈达庙铜矿床位于内蒙-兴安造山带西段之华力西晚期褶皱带内,哲斯敖包复向斜南翼,受北东—北北东向断裂构造及下二叠统大石寨组变质岩系控制.该矿区矿化体赋存于下二叠统大石寨组三岩段(P1d3)的英安质凝灰岩、凝灰岩中,严格受北东向断裂构造控制.铜矿体为含铜石英脉体,赋存于北东向断裂构造中.矿区内共圈定7个铜矿体,矿体总体走向为北东—北北东向,倾角4375°.铜矿体呈脉状、透镜状,有分支现象,厚度变化小,属稳定型.通过系统总结矿床的矿体地质、矿物成分、矿物嵌布及围岩蚀变特征,认为铜矿成矿与变质岩系、断裂构造、岩浆热液活动有关,矿床成因类型为岩浆热液型.

| Abstract: | The Chaganhadamiao copper deposit in Inner Mongolia,located on the south wing of Zhesiaobao synclinorium in the Late Variscan fold belt of western Inner Mongolia-Xingan orogenic belt,is controlled by the NE-NNE-trending faults and Lower Permian Dashizhai metamorphic formation.The orebodies,occurring as Cu-bearing quartz veins,are hosted in the dacitic tuff of the third member of Lower Permian Dashizai Formation.The deposit consists of 7 copper orebodies,which generally trend to NE-NNE,with dip angles between 43° and 75°.With study on the geology of deposit,mineral composition,mineral occurrence and wallrock alteration,it is suggested that the copper mineralization should be related to the metamorphic rocks,faults and magmatic hydrothermal activities.The deposit belongs to magmatic hydrothermal type in genesis. |
