湘西雪峰山地区金矿床地质特征及其分布规律

The geological features and the regularity of distribution of gold deposits in the Zone of Xuefeng Mountain, West Hunan

湖南西部热液型金矿床,包括钨锑金不同矿物组合的矿床,主要集中分布于江南地轴西缘雪峰弧形构造带的东段和中段,赋存于古老变质岩系及中新生代的构造——岩浆带中。主要成矿期为雪峰期和燕山期。区内的构造作用、岩浆活动及区域变质作用决定了各种类型的矿床是多源多成因的。

The hydrothermal type gold deposits including complex deposits of different mineral assemblage of tunsten, antimony and gold in western Hunan are distributed mainly in the eastern and middle sections of Xuefengian arcuate structural belt along the western margin of Jiangnan Geoaxis; occurred in ancient metamorphic rocks series and tectonicmagmatic belt of mesozoic and cenozoic era, The major metallogenic periods are Xuefengian and yanshanian, Various ore types in this region are of multiple sources and origins that resulted from magmatic activity and regional metamorphizm.
