Shaktau and Tratau Reef Mounds, Southern Urals (Permian to of Russian Federation)

Also known as Reef 214

Where: Bashkortostan, Russian Federation (53.6° N, 55.9° E: paleocoordinates 22.6° N, 42.8° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Shakhtau Reef Formation, Asselian to Asselian (298.9 - 290.1 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified bindstone and lithified framestone

• The Tratau Reef Mound is 270 m high and about 1 km in diameter. The total thickness is about 400 m. The Shaktau Reef Mound is 210 m high and 1.3 km in diameter. Reef-core facies are coral framestones, palaeoaplysinid platestones, Archaeolithoporella bindstones, Stromatactis-rich Tubiphytes bindstones and bryozoan bafflestones-cementstones.
