Magnified image of a polished surface of an oolite deposited in the Tambien Group of Ethiopia <15 m.y. before the onset of the ca. 717 Ma Sturtian “Snowball Earth” Glaciation. Each ooid grain is about 2 mm wide and likely formed in a tropical carbonate beach environment. This and other sedimentary rocks in the Tambien Group suggest a rapid change in this basin from warm marine conditions into an episode of severe glaciation. See ”The lead-up to the Sturtian Snowball Earth: Neoproterozoic chemostratigraphy time-calibrated by the Tambien Group of Ethiopia” by Park et al., p. 1119–1149.
