| 摘 要： | 赣东北断裂带处于江南台隆与钱圹拗陷的接合部位。由于该断裂带经历了长期发展演化及多种地质作用,致使赣东北断裂带控制该带多期多次构造—岩浆活动和铜、金的多期多次内生成矿作用。多期多次(活化)构造控矿模拟实验结果表明,活化构造不仅加剧了岩石、矿石的变形、破裂,为铜、金成矿提供良好的空间条件,并使原先分散在矿源层和矿源岩中的成矿物质产生活化、迁移,而且使成矿物质叠加、改造、富集成矿。

ACTIVATED STRUCTURE CONTROLLING ON COPPER AND GOLD MINERALIZATION IN FAULT BELFS IN NORTHEASFERN JIANGXI PROVINCE AND SIMULATING EXPERIMENT |
| |
| Abstract: | The fault belt in Northeastern Jiangxi Province is located in a conjunction between Jiangnan platformal dome and Qiantang sag.Polystages of tectonic-magmatic acti vities and those of copper-gold metallogenesis may be controlled by a long-term evolution of geologic pr ocesses.A simulating experiment on this fault indicated that activated structures not only reinforced defo rmations of rocks and ores but also provided hosting space for copper an d gold mineralization.Furthermore,the activated structures maybe forced the dispersed metallogenic materials in source rocks to be re-actived and to be migrated out of them as well as accumulation of metallogeni c materials and supermposition. |

| Keywords: | Activated structure Cu and Au mineralization simulating experiment fault belt in North-eastern Jiangxi Province |
