摘 要: | 自中元古代以来,湘东北地区经过多期次的构造活动,形成以EW向构造为基础,NNE向构造为主的构造特征,韧性剪切推覆带和长平断裂控矿作用明显,冷家溪群是金的预富层位,大万金矿区NWW向断裂构造是主要的容矿构造,主要成矿作用发生于燕山晚期,燕山期花岗岩体及其有关热液对金矿床形成有着积极的作用。

DISCUSSION ON THE TECTONOMETALLOGENIC BACKGROUND OF THE DAWAN GOLD ORE DISTRICT,NORTHEASTERN HUNAN PROVINCE |
| |
Abstract: | Northeastern Hunan Province have experienced polyphases structure movements since Middle Proterozic era and formed the structural characters which included EW-trending basement and NNE-trending cover,ductile thrust-shear zone an d Changsha-Pingjiang fault distinctly control gold orebodies,the Lengjiaxi Group is enriching strata of gold,th e NWW-trending faults of the Dawan gold deposit district are major ore-hosted structures and the main metallogenic epoch is late Yanshanian period,the granites of Yanshanian period and its related hot fluids pla y a great role in forming gold deposit. |

Keywords: | Northeastern Hunan Dawan gold deposit district structure metallogen ic background |
