中文摘要:
      [摘要]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。
英文摘要:
      Abstract:The Baizhangzi is one of the major gold deposits in the J idong gold mineralization belt, Liaoning. There are two types of gold mineraliza2 tion, 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 p roperty contrast between Orebodies and country rocks, at initial exp loration stage, resistivity - central gradient array, induced polari2 zation - central gradient array and induced polarization - sounding surveywere conducted. Orebodies show low resistivity and high polarization, anomalous zones are coincide with the main structures and granitic porphyry body, therefore, the exp loration targets are changed from the p revious focusing on the NW striking small orebodies to the area along the main structures and granitic porphyry body for concealed mineralization. The electrical anomalies were drill tested which intersected significantmineralization.
