摘要
构造叠加晕找矿方法在金矿床深部找矿勘查中取得了显著的找矿效果,本文研究表明:矿床严格受控于韧性剪切带,具有多期次成矿特征;单一成矿原生晕在纵向上自下而上表现为Sn-W-V-Mo-Bi→Pb-Zn→Au-Ag→As-Sb-Hg-B的变化规律;多期次叠加晕的前缘晕为As、B、Sb、Hg,尾晕为Bi、V、Mo、Sn、W,近矿晕为Au、Pb、Cu、Ag、Zn;根据叠加晕显示矿体下部存在隐伏矿体,经钻孔工程验证揭露隐伏盲矿体3处,找矿效果明显。
The construction overlay halo prospecting method has achieved remarkable ore prospecting effect in the deep prospecting of gold deposits,the research in this paper shows that the deposit is strictly controlled by the toughness shear belt,with multi-stage sub-mineralization characteristics;Single mineralization protohalos are represented in vertical bottom-up,bottom-up,sn-W-V-Mo-Bi,Pb-Zn,Au-Ag,As-Sb-Hg-B,and the leading edge of multiple-stage overlay halos are As,B,Sb,Hg,tailings are Bi,V,Mo,Sn,W,near-mine halos Au,Pb,Cu,Cu,Ag,Zn;according to the superimposed halo shows the existence of hidden ore body in the lower part of the ore body,the drilling project verification revealed the hidden blind ore body 3 places,the effect of prospecting is obvious.
