摘　　要：三道岔金矿床是吉林夹皮沟金矿区大型矿床之一,地处华北地块北缘东段,地块边缘裂谷型绿岩带之中.矿床严格受北西向弧形构造带及其次一级南北向构造控制.太古宙绿岩带、南北向脆-韧性剪切带、脉岩、矿体构成三道岔金矿床独特的地质环境,即"四位一体"地质成矿模式.低阻高极化缓衰减激电异常是矿体的直接反映,Au、Ag、Cu、Pb、As、F、Hg(气)等元素组合异常可以作为土壤地球化学测量找矿的评价指标.综合异常模式找矿是综合地学模式的一种应用.The Sandaocha gold deposit, occurring in the greenstone belt of massif marginal rift type in the east part of the northern margin of North China massif, is one of the large-scale deposits in Jiapigou gold ore field, Jilin province. It is strictly controlled by the NW-trending arc structural belt and the N-S-trending secondary structure. Archean greenstone belt, N-S-trending brittle-ductile shear zone, dike rock and ore body compose the particular geological setting of Sandaocha gold deposit, which is known as the ＂four-in-one＂ ore-forming model. The low-resistance, high-polarization and slow-attenuation abnormality of inspire polarization is the reflection of ore body. The synthetic abnormality of Au, Ag, Cu, Pb, As, F and Hg （gas） can be regarded as the assessment index of soil geochemical survey. Such a synthetic abnormality model is one of the applications of synthetic geologic model.
