河南省济源沙沟铅锌矿的发现及意义

    DISCOVERY AND SIGNIFICANCE OF THE SHAGOU LEAD-ZINC DEPOSIT IN JIYUAN, HENAN PROVINCE

    • 摘要: 根据化探异常所圈定的靶区,采用化探和物探相结合的方法,在河南省西北部上寒武统白云岩中发现了类似于MVT的铅锌矿床.矿体赋存于上寒武统的厚层状白云岩中,矿体的产出部位与层位和构造关系密切.不同级别和不同时期的构造相互交汇和切割,对铅锌矿床的形成起着明显的控制作用.通过矿床特征、找矿标志的分析研究,对该类型铅锌矿床的找矿标志和找矿方法有了新的认识和发现,为寻找此类型的铅锌矿床提供了经验.

       

      Abstract: Based on the target delineated by geochemical anomaly, combining geophysical method, the Jiyuan lead-zinc deposit, which is similar to the Mississippi Valley Type(MVT), is found in the Upper Cambrian dolomite in Northwestern Henan Province. The orebodies, occurring in thick-bedded dolomite, are closely related to the horizons and structures. The intersections of structures with different times and various levels obviously control the formation of the lead-zinc deposit. With the analysis on the characteristics and prospecting signs of the deposit, the new exploration methods on such type of lead-zinc deposits are concluded, which provide some experiences for further prospecting.
