| 摘 要： | 与广济－九江同步耦合断层对应的NNE向断裂（郯庐断裂、赣江断裂）经历了三次性质转变：J3－K1（157－97Ma)为左行走滑,K1晚期至E2为张性拱裂,E2－3以后呈右行走滑;在广济－九江同步耦合断层的耦合区内相应形成了伸展褶断、扭旋褶断、挤压褶断三种构造组成形式,其中燕山早期的伸展褶断构造组合呈现出张性伸展性质,为成岩成矿提供有利空间;同步耦合区内形成于燕山早期第二、三阶段的堑垒式褶断构造和燕山晚期第一阶段的扭旋褶断构造是控制成矿岩体及矿床定位的具体构造形式。 |

| Abstract: | Guangji-Jiujiang synchro coupling fault is located in the mineralization belt in the middle and down of Yangtze River,and controlls the ore forming process in the Jiujiang-Ruichang area of Jiangxi Province.Along with the three main changes of the property of the NNE fault (Tan-Lu fault and Gan-Jiang fault),and with the property of sinistral strike slip, tensional and dextral strike slip in J 3-K 1(157-97 Ma),and K 1-E 2 and after E 2~3 ,Guangji-Jiujiang synchro coupling fault possesses three main properties as extension, dextral strike slip and compression.Hence,three main kinds of structure forms occur in order:extension fault fold form,strike slip fault fold form and compression fault fold form,among which the extension fault fold form in early Yanshan period is the most important structure responsible for magmanism and mineralization in this area,while the graben horst fault fold form in the second and third stage of the early Yanshan period and the strike slip fault fold form in the first stage of late Yanshan period are the exact structures to control the mineral deposit of this area. |
| Keywords: | middle and down section of the Yangtze River Jiujiang-Ruichang mineralization belt synchro coupling fault controlling structure of magmanism and mineralization |
