内蒙古锡林郭勒盟宝力格地区侏罗纪火山岩地球化学特征及找矿潜力分析

Geochemical characteristics and prospecting potential of Jurassic volcanic rocks in Baolige area,Xilingol League,Inner Mongolia

宝力格地区广泛发育的侏罗纪火山岩,呈北东向条带状断续展布,受基底断裂构造的控制。依据火山岩展布规律、岩石组合特征、火山活动方式及基底分布特点等,分析研究了各时代火山岩形成的构造环境及岩浆来源,分析了研究区铜铅锌等有色金属矿产资源的找矿潜力及方向,为该区域进一步开展找矿勘查工作奠定基础。

Jurassic volcanic rocks are widely developed in Baolige area,which are distributed in NE trending bands and are controlled by basement fault structure.According to the distribution law of volcanic rocks,the characteristics of rock assemblage,the mode of volcanic activity and the distribution characteristics of basement,the tectonic environment and magma source of volcanic rocks in different ages are analyzed,and the prospecting potential and direction of copper,lead,zinc and other nonferrous metal mineral resources in the study area are analyzed,which lays a foundation for further exploration in the area.
