摘　　要：本文通过五台山地区典型地段—照山一带基岩地球化学测量及异常特征的研究 ,并结合区域地质、构造等特征的综合分析 ,提出Au、Ag、Cu、Bi、As为区域金 (铜 )矿地球化学勘查的最佳指示元素组合 ;确定出三个较为重要的矿化带 (区 ) :一个是下龙宿沟—上龙宿沟铜—金矿化带 ,另一个是土岭铁建造金矿化带 ,第三个是台峪口金异常区 ;金矿化的形成受条带状铁建造的发育程度以及区域变质变形作用过程中热流体活动的叠加改造等共同制约。Through the research work of rock geochemical survey and the characteristics of anomalies, associated with the comprehensive study of regional geological and structural characteristics, the authors of this article suggest that Au、 Ag、 Cu、 Bi、 As are the most important indicative elements for the regional geochemical exploration of gold (copper) mineralization; propose three more important mineralized zones and /or district: the fist is Xialongsugou—Shanglongsugou copper—gold mineralized zone, the second is Tuling BIF hosted gold mineralized zone, the third is Taiyukou gold anomalous district; and also suggest that the formation of gold mineralization controlled by the formation of BIFs (Banded iron formations), the superimposition of hydrothermal activity in the course of regional metamorphism and deformation etc..
