Geography
Country: | China | State/province: | Guizhou |
Coordinates: | 26.3° North, 106.7° East (view map) | ||
Paleocoordinates: | 13.3° North, 95.1° East | ||
Basis of coordinate: | based on nearby landmark | ||
Geographic resolution: | outcrop |
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?) |
