| 摘 要： | 湖南大新金矿床位于湘中白马山-龙山东西向成矿带中部的大乘山穹隆北东端。受区域基底断裂的分割与挟持,及其下伏岩浆活动的上侵作用,穹隆核部震旦系江口组地层发生脆性断裂,从而为成矿提供了导矿和容矿构造,矿区矿脉严格受NE、NW、近SN向三组断裂控制。矿床为破碎蚀变岩夹石英脉型金矿床,含矿热液沿断裂破碎带充填交代而成矿。 |
| 关 键 词： | 金矿床 构造控矿 矿床成因 湖南大新 |

| Abstract: | Daxin gold deposit in Hunan province is located i n the northeast edge of the Dachengshan dome, and specifically in the middle part of the Baimashan-Longshan E-W trending ore zone of the Xiangzhong ore district . A large number of brittle faults cut across the Sinian Jiangkou Group in the c ore of the dome. These faults, constituting the transmission and host structure of mineralization in the Daxin gold deposit, are probably resulted from activati on of the regional basic faults and emplacement of the underlying magmatic rocks . Formation of gold lodes was closely controlled by three groups of faults with NE-trend, NW-trend and N-trend respectively. The Daxin gold deposit possibly belong to the altered cataclastic rocks emplaced by the quartzose lodes, and may result from metasomatism and infilling of ore-bearing hydrothermal fluids alon g the fractural zones. |
