摘要
红道巷金矿区处在阴山断隆中的北西向小东沟糜棱岩带中段,矿区经历了早期的韧性剪切带发育阶段(糜棱岩带)和晚期的脆性构造发育阶段(硅化破碎带);金、钼、铜矿体具有垂向分带规律.金矿体主要分布在近地表,处于糜棱岩带上盘渣尔泰山群中发育的硅化破碎带中,并与石英脉关系密切;钼矿体主要分布在浅部,处于碎裂蚀变糜棱岩带中,与绿泥石化、绢云母化、黄铁矿化关系密切;铜矿体主要分布在深部,处于糜棱岩带上盘发育的铁硅质角砾岩带中,铜矿体围岩具有明显青盘岩化.
Hongdaoxiang gold field lies in the mid-zone of mylonite zone of Xiaodonggou which locates in the north-west of Yin Mountain fault.And it has gone through ductile development stages of shear zone（Mylonite zone） in the early and brittle structures（Silicified Fracture Zone）.The gold,molybdenum and copper ore body in the mid-zone have the characteristics with a vertical zoning law.The gold ore body mainly distributes in the near-surface,which locates in the Silicified fracture zone of Zhaertaishan Group in the hanging wall of Mylonite zone,and is closely related to the quartz vein.The Molybdenum ore body mainly distributes in shallow,locating in the crack and alteration Mylonite zone,and is closely related to chloritization,sericitization and pyritization.The copper ore body mainly distributes in deep,and locates in the iron and Siliceous breccia zone in hanging wall of Mylonite zone,where the rock alteration of the copper ore body has clear propylition character.
