Lek-Elets River reef, Polar Urals (Devonian to of Russian Federation)

Also known as Reef 2249

Where: Komi, Russian Federation (67.4° N, 65.2° E: paleocoordinates 6.1° N, 7.2° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Pragian to Pragian (410.8 - 393.3 Ma)

• Pragian part: 360 m thick and 5 km long, Lower Emsian part: 220 m thick and 2 km long

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified reef rocks

• Grey massive wackestones and skeletal packstones form the reef base. Light-grey algal-stromatoporoid boundstones, associated with Ikella-Fistulella and Solenopora-metazoans boundstones are also common. The Lower Emsian part is an alternation of microbial-stromatoporoid boundstones, mudstones with Stromatactis and skeletal packstones.

Size class: macrofossils
