Abstract: On the basis of comprehensive collecting and integrating of existing research achievements, and the new samples collected in the field in typical regions of Hubei, the authors analyzed the geological characteristics of different Se resources, and discussed their potential exploitation and utilization. The results show that the Se-enriched strata were Cambrian (32.1%), Permian (29.8%) and Sinian (25.8%), respectively. The Se-enriched rocks were mainly carbonaceous shale, carbonaceous slate, siliceous rock, carbonaceous siliceous rock and carbon-containing shale. The Se-enriched soil was mainly derived from lacustrine and alluvial deposits, and was distributed in the regions of Jianghan Plain, Enshi and southeastern Hubei. In particular, the distribution of Se-enriched soil in Enshi was in accordance with the distribution of Se-enriched Permian strata in this area and the Shuanghe Se mine and mineralized points in Enshi. The Se-enriched soil in southeastern Hubei, on the other hand, was related to both the Permian strata and the Se associated-deposit in this region.
Keywords: Se-enriched resources   Se-enriched strata   Se-enriched soil   Hubei
