辽宁生金皋和赵家堡子金矿黄铁矿的找矿标志

在辽宁生金皋地区和赵家堡子地区的找金过程中,采用黄铁矿矿物学方法,对黄铁矿晶体的形态、主要成份和微量元素特征等进行分析。结果表明以五角十二面体晶形为特征的半自形细粒状黄铁矿含金性较高;黄铁矿主成份S、Fe含量相对低,而黄铁矿中Cu、Pb、Zn、Au、Ag等微量元素总量相对高的黄铁矿分布区域与金矿化关系密切;提出赵家堡子地区具备找到一处中型以上金矿的前景,而在生金皋地区找到大型金矿床的可能性很小,但有望找到伴生金矿床。

On ore guides in pyrite from Shengjingao and Zhaojiapuzi gold deposits, Liaoning

Based on mineralogical methods,the authors analyze the characteristics of pyrite from the Shengjingao and Zhaojiapuzi areas of Liaoning in crystal form,main components and trace elements.The results show that the fine-grained hypidiomorphic pyrite,with a crystal form of pentagonal dodecahedron,contains more Au than others.Since the areas yield pyrite with relatively lower contents of main components S and Fe,while a greater gross content of trace elements,such as Cu,Pb,Zn,Au,Ag,are closely associated with gold deposits,the authors propose that a middle-scale gold deposit might be found in Zhaojiapuzi area;and there is a remote possibility to find a large gold deposit in Shengjingao area,wih a prospect of finding a concomitant gold deposit.
