New occurrence of native selenium and its preliminary investigation

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.
