"Ediacaran Cordilleran-type mountain ice sheets and their erosion effec" by Ya zhuo Niu, G. R. Shi et al.

Glacial erosion has long been recognized as a significant factor contributing to continental denudation during the Ediacaran Period, consequently leading to geochemical perturbations and biotic evolution in marine environments. However, the role of Ediacaran glaciation in the oceanic geochemical perturbations remains controversial due to ambiguous geochronological correlations and unresolved paleogeographic and tectonic settings. A total of 45 Ediacaran glacial records have been reviewed and categorized into four Ediacaran glaciations: Gaskiers (581–579 Ma), Fauquier (ca. 571 Ma), Bou-Azzer (ca. 565–560 Ma), and Hankalchough (ca. 562–551 Ma) glaciations. Of these glacial records, 53% have been reported in the Avalonian–Cadomian and Altaids accretionary orogenic belts, recognized as representing Cordilleran-type mountain ice sheets (CMISs). This study reports an Ediacaran glaciation in the southern Altaids, NW China, with 18 glacial and non-glacial facies and 1173 new U-Pb-Hf da
