辽宁铁岭夹河厂地区水系沉积物测量地球化学特征及找矿方向

Geochemical Characteristics and Ore Search Prospects of Jiahechang Area in Tieling of Liaoning Province Based on Stream Sediment Survey

在1∶5万水系沉积物测量的基础上,对辽宁省铁岭市东南部夹河厂地区的地球化学特征进行了初步分析,发现夹河厂地区以Au、Ag异常为主,伴生有Pb、Hg、Bi、As、W等多元素异常。对元素分布特征、相关性分析、单元素异常特征等进行了探讨,综合分析认为Au、Ag、Pb为区内具有一定找矿潜力的元素。依据水系沉积物异常的解释推断,结合区内成矿地质构造背景,进而划分出夹河厂金矿、沔阳沟金矿、大碾子沟金矿及昂帮河铅银多金属矿找矿远景区。

The preliminary study of the geochemical features in Jiahechang area of southeast of Tieling in Liaoning Province was based on the 1：50 000 stream sediment survey,the combination anomaly of multiple elements were dominated by Au,Ag and accompanied with Pb,Hg,Bi,As,W.The study included element distribution characteristics,element correlation and element anomalies.The result shows that the Jiahechang area might be a prospective area for Au,Ag,Pb.According to the interpretations of geochemical anomalies and combined with the metallogenic background in the aspects of strata and structure,Jiahechang,Mianyanggou and Danianzhigou areas are found to be prospective areas for Au deposits,the Angbanghe area is to be a prospective area for Pb-Ag polymetallogenic deposits.
