Stratigraphy
Formation:Qingyan
Stratigraphic resolution:group of beds
Stratigraphy comments: Bed 4 (units KC 259-262) is 80 m thick. About 200 m above base of Qingyan Formation.
Lithology and environment
Primary lithology:gray,green,yellow lithified "shale"
Secondary lithology:gray lithified marl
Lithology description: Qingyan Formation consists mainly of gray to yellowish-green noncalcareous shale, pale-to dark-gray marl, calcareous shale, and argillaceous limestone, usually thin-bedded. Most of the fossils are collected from the shale and marl.
Environment:marine indet.
Geology comments: Evaporative basin in Sichuan and north Guizhou separated from open marine to south in Yunnan and Guangxi by biohermal belt, located just north of Qingyan. The area near Qingyan was a prebiohermal facies. (Apparently fore-reef or something equivalent, located on the slope?)
