龙潭里金矿成矿地质条件及找矿方向分析

Analysis of metallogenic geological conditions and prospecting direction of longtanli gold deposit

矿区位于地处郯庐断裂带皖东段中部,岱山-管店岩体与张八岭岩群接触带之东缘,管店岩体为本区金矿形成提供了物源和热源,区域性断裂带控制了岩浆活动和岩浆岩展布,并派生出一系列多级别的对成矿作用有利的导矿和容矿次级断裂构造,形成构造蚀变岩型夹石英脉型金矿;矿化构造蚀变带位于铜狗城西北部,西冷岩组地层中,产出于断裂内。

The mining area is located in the middle part of the eastern Anhui section of the Tan Lu fault zone,and the eastern edge of the contact zone between Daishan Guandian rock mass and Zhangbaling rock group.Guandian rock mass provides the material source and heat source for the formation of gold deposits in this area.The regional fault zone controls the magmatic activity and the distribution of magmatic rocks,and derives a series of multi-level ore guiding and ore containing secondary fault structures favorable for mineralization,forming structural erosion The mineralized structural alteration zone is located in the northwest of tonggoucheng,in the xichunyan formation,which occurs in the fault.
