The Upper Permian Xuanwei Formation widely occurs in western Guizhou, unconformably overlying the Emeishan basalts, and mainly consists of black shales. It is ∼170 m thick at Cuyudong Village, Weining County, West Guizhou, China, where the samples of black shale and sandy shale were collected and analyzed. The shales mainly contain SiO2, 18.9%–44.1%, Al2O3, 14.8%–52.8%, Fe2O3, 1.0%–41.2%, LOI, 3.2%–21...
