Geography
Country: | China | State/province: | Nei Mongol |
Coordinates: | 42.0° North, 110.0° East (view map) | ||
Paleocoordinates: | 23.5° South, 108.8° East | ||
Basis of coordinate: | estimated from map | ||
Geographic resolution: | local area |
Stratigraphy
Formation: | Xibiehe | ||||
Stratigraphic resolution: | formation | ||||
Stratigraphy comments: Except where otherwise stated, ref. 7624 uses Lower Silurian as equivalent to Llandovery, Middle Silurian as equivalent to Wenlock, and Upper Silurian as equivalent to Ludlow plus Pridoli. Original description placed formation in Mid Devonian, but "Li Wen-guo et al. (1979) consider this fauna to be of Late Ludlow to Pridoli age, chiefly on the basis of the brachiopods and stromatoporoids." |
Lithology and environment
Primary lithology: | gray,green sandstone |
Secondary lithology: | shelly/skeletal "limestone" |
Includes fossils? | Y |
Lithology description: "The unit consists chiefly of gray and greenish-gray, coarse-grained, quartzitic sandstone, and micaceous siltstone, with interbedded, thin-bedded, bioclastic limestone, and reef limestone rich in fossils. The thickness is 357 m." | |
Environment: | marine indet. |
Geology comments: Correlation chart indicates BA3 based on shelly fauna. |
