摘要
建阳江墩金矿呈脉状-(长)透镜状,赋存于矿化蚀变体内或其边缘,与金矿形成关系密切的矿化蚀变体产于下元古界麻源群大金山组上段变质岩系的F6断裂蚀变带中。共发现表内金矿体9个,表外金矿体3个,规模较小,品位较高。初步认为矿床类型属于与变质热液有关的构造蚀变岩型金矿床。
The Jiangdun gold mine in Jianyang County exists in the insides or margins of mineralizing altered rock as veiny or long lentiform. The mineralizing altered rock Which is a close relation with the formation of gold ores is discovered in the altered zone of the F6 Fault which is located at the metamorphic rock series of Lower Proterozoic Mayuan Group Dajinshan Formation. The twelve gold orebodies are discovered in the surveyed area and they are characteristic of smaller scale and higher grade. It is considered that it belongs to the gold field of the tectonic altered rock type which is relative to the metamorphic-hydrothermal solution.
