激电法在辽宁柏杖子金矿勘查中的作用及意义

辽宁柏杖子金矿床是冀东金矿带大型金矿之一,金矿化类型为含金黄铁矿石英细脉浸染型和含金黄铁矿石英脉型,大部分金矿矿体是隐伏矿体,矿体与围岩电性差异明显,矿床普查阶段开展了电阻率中梯测量、激电中梯测量和激电测深工作。矿体具有低阻高极化特点,异常带与矿区主构造和花岗斑岩吻合一致,因此由以往围绕北西向小矿体找矿,改变为沿矿区主构造和花岗斑岩寻找隐伏矿体,根据电法异常布设钻孔,取得了显著找矿效果。

The Applica tion and S ign if icance of the Induced2polar iza tion Method in Explora tion of the Ba izhangz i Gold Deposit in L iaon ing

The Baizhangzi is one of the major gold deposits in the Jidong gold mineralization belt,Liaoning.There are two types of gold mineralization,one is auriferous disseminated pyrite and fine pyrite-quartz veins,the other is auriferous pyrite-quartz lodes,most orebodies are concealed.There is obvious electrical property contrast between Orebodies and country rocks,at initial exploration stage,resistivity-central gradient array,induced polarization-central gradient array and induced polarization-sounding survey w...
