湘西雪峰地区金多金属成矿带研究进展

Advance Research of Au Multi-metal Metallogenic Belt in Xuefeng Region,Western Hunan Province

对湘西雪峰地区金多金属矿床的成矿物质来源、成矿时代及控矿构造等方面的成果进行了总结,认为该区金多金属成矿带为一控矿构造复杂,具有多期、多源特征的复成矿带,NE、NW、EW和SN向构造及其次级构造为该区重要的控矿构造,存在赋矿地层、下伏更老的结晶基底以及后期含矿热液等多种成矿物质来源,加里东期和印支期可能为该区重要的金多金属成矿期。这对于全面了解雪峰地区的成矿作用有一定的参考意义。

Based on previous research work,this paper summarizes the structural ore controlling,source of metallogenic materials and metallogenic ages of Au multi-metal metallogenic belt in Xuefeng region.This paper proposes that Au multi-metal metallogenic belt is a complex metallogenic belt,with complex ore-controlling structure,multiple sources of metallogenic materials and metallogenic ages.NE-,NW-,EW-and SN-trend structure may be the important ore-controlling structure.Ore-bearing strata,crystalline basement under ore-bearing strata and ore-bearing hydrothermal may be provide metallogenic material.Caledonian and Indosinian may be the important Au multi-metal metallogenic epoch.It may have referential meaning on overall understanding metallogenesis of Xuefeng region.
