摘要
1.Objective The Qinglong area is located in the Eastern Yunnan- Western Guizhou uplift tectonic belt, west of the Zishui fault zone and north of the Youjiang basin. There are many sets of organic-rich shale in Longtan Formation in Qinglong area. Many predecessors did a great deal of research on the geological features of Permian coal fields in Western Guizhou (Mei MX et al., 2004;Dou XZ et al., 2012), but lack of the research on sedimentary background and distribution characteristics of organic-rich shale in Longtan Formation. Therefore, this study focuses on the analysis of the sedimentary environment of the Upper Permian Longtan Formation in Qinglong area.
