摘　　要：文中通过吉林省靖宇县那尔轰镇大东沟、小东沟两处化探异常查证中,利用地质、化探、激电法等综合方法找矿的成功实例。提出了在化探异常查征中地质、土壤测量、激电等合理的工作程序和评价异常最经济有效的方法组合。所建立的物化探"两高一低"即高极化率、金多金属元素含量高、低电阻率的综合找矿模型,结合地质因素,对在该地区找寻构造破碎蚀变岩型的贵金属及金属硫化物矿体(矿化体),具有明显的指导作用。进一步证实了在1:1万矿产勘查工作中推广应用综合信息,建立"模型"指导地质找矿的重要性和必要性。In geochemistry reconnaissance of Dadonggou and Xiaodonggou,Narhong Town,Jingyu County,Jilin Province,using comprehensive methods of geological,geochemical prospecting,IP,proposed the reasonable working procedures in geological,soil survey,IP,evaluated the most cost-effective abnormal method,and established comprehensive prospecting model with high polarizability,high content gold polymetallic elements,and low resistivity,It has an obvious significant guidance for prospecting fractured altered rock type precious metals and metal sulfide orobodies in the study area,and further confirmed prospecting importance and necessity of modeling in 1：10000 mineral exploration works.
