摘　　要：本文总结了在金矿老矿区开展综合物化探方法“就矿找矿”的经验;提出了金矿找矿综合评价参数的概念;在实际应用中取得了明显的效果。利用综合评价参数异常类比法进行了金矿储量预测。航电异常检查和综合地球化学填图为矿区外围找矿指明了方向。The present paper outlines the experience and understanding in gold exploration in exhausted min-ing areas by using comprehensive geophysical-geochemical survey.Parameters measured by various me-thods used are normalized and weighted to give a comprehenive evaluation parameter which in its pr-ectical applications yielded tangible results.With the help of this parameter satisfactory results wereobtained in gold ore reserve prediction,in ground follow-up of airborne electromagnetic survey,and in-tegrated geochemical mapping.Some areas,outside old mining districts,favourable for orehunting,weredelineated in this way.
