【摘要】 通过对三道湾子金矿床构造叠加晕研究,表明Au是形成金矿体的最直接、最重要的指示元素,Ag是重要伴生元素。As、Sb、Hg是金矿的前缘晕特征指示元素。Cu、Pb、Zn强异常反映Ⅱ阶段叠加,可能形成富矿体。Bi、Mo、Mn、Co是尾晕指示元素。经计算分带序列,发现Sb、As、Hg前缘晕元素出现在分带序列的下部,出现反分带,反映了矿化叠加。建立矿床构造叠加晕模式,并成功预测深部盲矿靶位。更多还原

【Abstract】 Study on Sandaowanzi gold deposit Structural superimposed halos Shows that the direct and important indicator element of ore-body is Au,Ag is the important associated element,the front halo indicator elements of ore-body are As,Sb,Hg.The strong anormalies of Cu,Pb,Zn show the second stage mineralization superimposed.the rich ore bodies were formed there maybe.Rear halo indicator elements are Bi,Mo,Mn,Co.Obtained Sequence of element zoning by calculation,we find that the front halo indicator elements of ore-body As,Sb,Hg are appeared in the lower of the Sequence of element zoning.Appearante of abnormal bandings in the research of axial banding of primary halos,It shows the second stage mineralization superimposed. We establish the model of structure superimposed halo. Using the structural superimposed halo model and geological-structural superimposed halo signs,the blind ore-bodies targets in Sandaowanzi gold deposit deep are successfully predicted.更多还原
