| 摘 要： | This report describes the first occurrence of the rare mineral mandarinoite (Fe3+2 Se3Og · 6H2O) in China. It occurs in the Lower Permian Maokou Formation carbonaceous shale in Yutangba Village east of Enshi City in southwestern Hubei Province. The shale is selenium-rich and contains native selenium, V-Mo-Cr-bearing iron oxide, clay and quartz. Weathering of the selenium in the bedrock under moderate to high redox conditions in the presence of ferric iron has formed mandarinoite.

| Abstract: | This report describes the first occurrence of the rare mineral mandarinoite (Fe3+2 Se3 O9@ 6H2O) in China. Itoccurs in the Lower Permian Maokou Formation carbonaceous shale in Yutangba Village east of Enshi City in south-western Hubei Province. The shale is selenium-rich and contains native selenium, V-Mo-Cr-bearing iron oxide, clay andquartz. Weathering of the selenium in the bedrock under moderate to high redox conditions in the presence of ferric ironhas formed mandarinoite. |
