| 摘 要： | 高凡银金矿床黄铁矿的微量元素研究发现富Au、Ag、Pb、Zn、As、Sb,贫Co、Ni、Se,且S/Se较大,S/As和Fe/(Pb+Zn)较小,As/(Co+Ni)、(Pb+Zn)/(Co+Ni)>10。同时高凡矿田中的滩上铜钼矿化点的黄铁矿则显示相反的特征。总结出一套区分两类矿化黄铁矿微量元素的标型特征,对高凡矿田和五台地区各矿化点的判别和评价中显示了一定的适用性,可作为本区寻找同类金银矿床的找矿标型特征。

| Abstract: | The study fo trace elements of pyrites in Gaofan Ag -Au shows that the pyrite is rich in Au,Ag,Pb,Zn, As,Sb,poor in Co,Ni,Se with higher value of S/Se and lower S/As,Fe/(Pb+Zn) ;contrasting to the features of pyrites in Tangshan Cu -Mo mineralization with As/(Co+Ni)>10,(Pb + Zn)/(Co+Ni)>10 .The trace element typomorphic characteristics of pyrite summaried from Gaofan orefield are suitable in some degree to distinguishing and assessing the prospects in Wutai district ,and can be used as a prospecting typomophic characteristic of looking for this type of Au-Ag deposits in this area. |
