Leimingdong reef complex, reef core (Devonian of China)

Also known as Reef 1607

Where: Hunan, China (27.8° N, 111.6° E: paleocoordinates 4.1° S, 115.0° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Qiziqiao Formation, Givetian (387.7 - 382.7 Ma)

• member-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified reef rocks and lithified, fine-grained, calcareous bindstone

• "reef rock" from reefbuilding corals with fine grained matrix; the rock consists mainly of skeletal elements of reefbuilding corals, 50% to 90%.

Size class: macrofossils

Collection methods: mechanical,

• the reefcore is divided in two sections in which the abundance of the fossils changes.

•Lower part: Stromatopora 45%, Hexagonaria 30%, Alveolites 6%, between the rest Thamnopora and Temnophyllum are most abundant.

•Upper part: no Hexagonaria, Stromatoporoids 60%, Alveolites 10%, Rugosa and Tabulata are increased to 29%, from which Crassialveolitella and Alveolitella are relatively rich (about 2/3) and Thamnopora (about 1/3).
