摘　　要：基于潭玉沟S101银矿床特征及热液成矿理论,选取As、Sb、Hg为银矿的前缘晕特征指示元素,选取Ag、Cu、Pb为近矿指示元素,选取W、Mo、Bi、Sn为尾晕特征指示元素。构造叠加晕研究表明,矿体内前缘晕与尾晕叠加,原生晕轴向分带序列出现反分带,反映了多次矿化叠加。运用构造叠加晕盲矿体预测标志,对S101-Ⅰ号矿体深部找矿有利区进行了预测研究,提出了1处找矿靶区。Based on Tanyugou silver deposit geological characteristics and the theory of hydrothermal deposits,the front halo indicator elements of ore-body are As,Sb,Hg.Near halo indicator elements are Ag,Cu,Pb.Rear halo indicator elements are W,Mo,Bi,Sn.Obtained sequence of element zoning by calculation,appearance of abnormal bandings in the research of axial banding of primary halos shows the second stage mineralization superimposed.Using structural superimposed halo signs of the blind ore-bodies,one targets of blind ore-body are predicted in Tanyugou mining area.
