土壤地球化学测量在姚村矿区找矿中的应用

姚村矿区地处新桥式岩浆期后热液成矿地带,为查明矿区萤石矿成矿作用的地球化学特征,开展了1∶2.5万土壤测量勘查工作。通过土壤地球化学测量,运用Geochem Studio、SPSS软件对原始数据进行分析处理,结合矿区地球化学背景,圈出氟、金、银、铜、铅、锌等元素浓度高低不一、规模大小不等的具三级浓度级别以上的单元素异常55处,并经综合分析元素异常特征后得出综合异常4处。综合异常AP1为F-Mo-W-As,AP2为Pb-Zn-As-Sn,其成矿条件较好;AP3、AP4均有一定的铅、锌矿找矿前景。通过AP1以氟为主的多元素异常解释及异常查证,确定AP1为萤石矿的主要成矿靶区。

Application of soil geochemical survey to ore prospecting in Yaocun mining area

Yaocun mining area is located in the post-Xinqiao style magmatic hydrothermal metallogenic zone.In order to make clear of the geochemical characteristics of the fluorite mineralization soil surveys at scale 1∶25000 have been carried out in the area.The data obtained were analyzed and processed by Geochem Studio and SPSS software.Combined with the geochemical background are located 55 single element anomalies with three levels of concentration and different sizes and concentrations of fluorine,gold,silver,copper,lead,zinc etc.Comprehensive analysis of element anomly characteristics shows 4 comprehensive anomlies of wihich AP1 is F-Mo-W-As anomaly,AP2 Pb-Zn-As-Sn,and anomaly AP3、AP4 potential for lead and zinc prospecting.After interpretation and check anomaly AP1 is determined a fluorite tarhet.
