Where: Yakutsk, Russian Federation (60.3° N, 117.1° E: paleocoordinates 36.0° S, 3.3° W)
• coordinate estimated from map
When: Ura Formation, Ediacaran (635.0 - 541.0 Ma)
• Early Ediacaran
• group of beds-level stratigraphic resolution
Environment/lithology: deep subtidal shelf; lithified, gray mudstone and lithified siltstone
•of a thick sedimentary and volcanic rock succession, reaching up to ca. 5–7 km in total composite thickness.
•It has been suggested that they represent marine shelf and platform facies of cratonic passive margin (Khomentovsky and Postnikov, 2001), or a carbonate platform and rimmed shelf leading to a deep-water open shelf (Melezhik et al., 2009). Alternatively, strata were deposited in an active margin of the foreland basin adjacent to back-arc and subducting zone of ocean basin (Chumakov et al., 2007; Nemerov et al., 2010).
•interval of 3-15 m above the section base in an exposed succession
•of c. 20 m thick deposits.
