| 摘 要： | 在湖北恩施渔塘坝发现了罕见的自然硒矿物，同一地域内产生自然硒矿物的规模和多种成因类型并存的现象为首次报道。按自然硒的形成环境和赋存条件可将其分为三种，分别是碳质硅质岩和硅质碳质页岩中的原生自然硒，表生环境氧化还原作用形成的自然硒和“石煤”自燃形成的自然硒晶体。自然硒矿物的发现将为硒的矿物学、矿床地球化学和环境地球化学提供新的认识和研究空间。 |

| Abstract: | The native selenium has been discovered in Yutangba of Enshi City, Hubei Province, China. It is first found in such a small landscape in the world that native selenium produced is so large in scale and it varies morphologically due to different mechanisms. Native selenium is divided into three types based on its own occurring environments and conditions, which are native selenium in carbonaceous siliceous rocks and siliceous carbonaceous shale, redox (including biomineralization) series and crystals of selenium series derived from native burning of “ stone coal” . The new occurrence of native selenium found in China would be helpful to further study on mineralogy, ore geochemistry and environmental geochemistry of selenium. |
