摘要
本文利用地质、物化探、遥感资料综合分析了晋东北地区金矿的控矿因素。早前寒武纪结晶基底与金成矿关系密切，五台超群中的含铁建造是重要的金矿源层。利用断裂构造原生晕和元素分带性确定了含矿断裂；通过对燕山期侵入体的物化探特征研究，确定出２５个含金岩体；叠加型异常是该区找矿的重点靶区。
Based on data of geology, geophysical-geochemical prospecting and remote sensing the geological background of metallization and ore-controlling factors for gold deposits in northeastern Shanxi are studied. The results indicat that the early Precambrian crystalline basement has close relation to metallization, and the iron-bearing formation of the Wutai Supergroup is an important source bed of gold deposits. Ore-bearing faults are determined by analysing of faults, primary anomalies and elementary zonation. 25 gold-bearing magmatic bodies are determined by analysing geophysical-geochemical characteristics of the Yanshanian intrusions. It is indicated that stacked anomalies are the main prospecting targets.
