摘　　要： 湘东北近年来已相继勘探出多个金矿床,如黄金洞、万古、七宝山矿床等,其中黄金洞和万古金矿床均达到大型规模。该地区主要金矿床均赋存于中元古界冷家溪群地层中,是典型的受韧性剪切带控制的矿床。本文试图根据该地区已有的研究基础,结合近年来湖南省核工业地质局311大队在黄金洞—万古地区金矿地质工作取得的一些成果,从构造成矿学角度探讨本地区金矿的成矿机理和构造定位机制。 In recent years, several gold deposits, such as Huangjindong deposit, Wangu deposit, Qibaoshan deposit, etc., have been discovered in northeastern Hunan province, of which the Huangjindong deposit and Wangu deposit have reached large- scale. Most of the gold deposits in this area are located in the Mesoproterozoic Lengjiaxi formation, typically controlled by ductile shear zone. Based on the existing research findings in this area and the recent findings by 311 Brigade of Hunan Nuclear Geology in Huangjindong - Wangu zone mining geology, we tried to discuss the mineralization mechanism and tectonic orientation mechanism of gold deposits in this area from the perspective of structural metallogeny.
