摘要
水洞地区位于吉林省东部,处于天山—兴安地槽褶皱区,吉黑褶皱系延边优地槽褶皱带内,是我国比较重要的金成矿带之一[1]。本文介绍了该区的地层、构造、岩浆岩情况。通过化探分析确定了Au元素异常范围,且物探异常区与相应的化探范围内蚀变带相吻合,为该区寻找浅成中、低温热液型金矿奠定了基础。根据野外勘查工作中的实际情况对该区的找矿前景进行预测。
The Shuidong area located in the Tianshan-Xing＇an geosynclinal fold region, in the eastern of Jilin Province, also located in the Yanbian eugeosynclinal fold belt of Jihei fold System. It is one of important gold metallogenic belts in China. In this paper, the writers introduce the stratum, structure, magmatite in the area. By geochemical analysis to determine the range of Au element anomalies, and geophysical anomalies area coincide with alteration zones in the corresponding geochemical range, which laid the foundation for the prospecting of shallow-seated mesothermal-epitherm type gold ore in the area. The exploration prospect in the area was predicted according to the actual situation of the fi eldwork.
