| 摘 要： | 湘西是金，砷，锑，汞等有色金属的重要成矿带。区域地层微量元素地球化学研究表明，湘西所出露的地层均显著富集砷，是砷的高区域地球化学异常区，元素存在相态实验进一步表明，新元古界至寒武系中的砷以易迁移形式为主，新元古界至寒武系可能构成砷矿矿源层。其风化所成土壤中砷的含量也一定较高。 |

| Abstract: | Western Hunan is a main ore-forming zone for Au,As,Sb,Hg and other metal.The study on regional strata trace elements shows that the strata of Western Hunan has rich arsenic.The experimental geochemical study on arsenic speciations in the strata also indicates the speciations of arsenic in the Neoproterozoic-Cambrian strata are mainly movable fractions(exchangeable,bound to sulfides,bound to carbonates).So the Neoproterozoic-Cambrian strata in Western Hunan are probably main source beds of arsenic in the region,arsenic content in soil weathering from under rock are possible higher. |
