    摘要:

    刘山岩铜锌矿位于河南省桐柏县城北西25km的桐柏山北麓,处于东秦岭造山带之北秦岭褶皱带核部。矿体赋存于纹层状硅质-钠长石岩层中,矿石具纹层状、原生角砾状构造等,自矿体中心向边缘存在黄铁矿-黄铜矿-方铅矿-重晶石-石英的相对矿物分带。异常的浓度与组分分带反映的是一定时间域内成矿作用的延续与变化,纵向与轴向上具相同的组分分带,由中心至边缘的组分分带为Cd、Ge、Bi、As、Ga、Cu、Mo、Zn、Pb、Ag、Ba、Mn、V、W。根据异常元素组合、强度及其比值可以判断矿体剥蚀程度。重要的是,湿热条件下块状硫化物矿床赋矿岩系水系沉积物中成矿元素的贫化率极高,充分运用海底火山喷流相模式和圈定微弱、局部地球化学异常是勘查工作的根本手段。

    Abstract:

    The Liushanyan copper- zinc deposit lies in the layer of laminated siliceous albitite.The ore shows laminarand prim ary brecciated textures. From the center to the margin of the orebodies there shows a comparativemineral zonation of pyrite- chalcopyrite- galena- barite- quartz. The concentration and component zonationof anomalies shows the duration and changes of mineralization within a certain geological time domain.Thesam e component zonation is seen in the horizontal and axial directions,and from the center to the m argin,itshows a zonation of Cd— Ge— Bi— As— Ga— Cu— M o— Zn— Pb— Ag— Ba— M n— V— W . According to theassemblage,intensity and ratio of the anom aly elements the denudation degree of orebodies can be determined.The most important is that stream sediments of the host rocks of the massive sulfide deposit have an extremelyhigh dilution rate under humid and hot conditions.M aking best use of the subm arine thermal water eruptionfacies m odel and outlining weak and local geochemical anomalies are the fundam ental means in geologicalexploration
