Chuanshangou section, Chuanshangou Formation, middle member (Carboniferous of China)

Also known as Chuanshangou section, Chuanshangou Formation, near Haoluge, China

Where: Qinghai, China (37.0° N, 96.0° E: paleocoordinates 22.2° S, 56.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Middle Member (Chuanshangou Formation), Tournaisian (358.9 - 346.7 Ma)

• Accoroding to the scheme proposed by Wang(1987,1990), the Early Carboniferous sequence is bracketed between the underlying Ordovician and overlaying Upper Carboniferous, and comprises the Chuanshangou, Chengqianggou, and Huaitoutala Formations in ascending order.

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; lithified siltstone and lithified mudstone

• Lithologically, the Chuanshangou Formation can be further subdivided into the lower, middle and upper members, typified respectively by conglomerate, mixed sandstone, mudstone, and argillaceous limestone.

Size class: macrofossils

Collection methods: Collected by Li-Pei Zhan from 1976 to 1983. The specimens are housed in the Department of Invertebrate Paleontology, Museum of Victoria (NMV P).
