内蒙古东乌旗某铅锌矿床化探异常特征与找矿

摘要

东乌旗位于内蒙古中部—兴安地槽褶皱区、兴安地槽褶皱系(Ⅲ)、东乌旗早华力西期地槽褶皱带(Ⅲ12)南翼,巴音宝力格隆起带东部,中生代岩浆岩带西侧;燕山期岩浆岩是矿区的成矿母岩,断裂构造带内为矿体赋存的主要场所;研究表明Ⅱ号和Ⅶ号综合异常区是Pb、Zn、Ag等成矿元素的主要异常区,且Pb、Zn、Ag等成矿元素套合性较好;研究区具有良好的找矿前景.%Dong Ujimqin banner is located in central Inner Mongolia,including Xingan geosyncline zone,Xing'an geosyncline fold system (Ⅲ),south-wing of early Variscan geosyncline fold belt (Ⅲ12) in Dong Ujimqin banner.East of Bayinbaolige zone and West of Mesozoic Magmatic Rock Belt,including Magmatic rocks of Yanshan stage are all the metallogenetic parent rocks,as is a main place of ore bodies of tectonic fracture zone.The study shows that Ⅱ and Ⅶ comprehensive anomalous area is the main abnormal area of the ore-forming elements,such as Pb,Zn and Ag.Ore-forming elements,such as Pb,Zn and Ag,are coincided with each other.
