358高地岩金矿位于位于完达山地体东缘,矿体主要赋存于强硅化、褐铁矿化的花岗斑岩中,其围岩主要为晚白垩世花岗斑岩。目前为止,矿区内共发现3条矿化带,5条矿体,其分布形态与区内物化探研究成果吻合。笔者结合物探相关资料,对矿区内岩石、构造及其沉积环境的研究表明,本矿区的成矿类型是与隐爆角砾岩有关的浅成低温热液矿床特征。且本区具有较大的找矿前景。
Located on the eastern margin of the Wandashan Geological Deposit, the 358 high-grade gold deposit mainly occurs in the highly silicified and limonitic granitic porphyry, with the main surrounding rock being Late Cretaceous granitic porphyry. So far, a total of three mineralized zones and five ore bodies have been found in the mining area. Their distribution patterns are consistent with the results of geophysical and geochemical exploration in the area. Based on the related data of geophysical exploration, the author has made a study of the rock, structure and depositional environment in the mining area. It shows that the metallogenic type of this mining area is characterized by epithermal breccia-related epithermal deposits. And this area has a larger prospecting prospect.
