The Ediacaran glacial deposits are developed in the North China Craton, Tarim Craton and the microblocks among them, where they can extend for 3000 km from east to west. However, the chronology, scale of glaciation, paleogeographic reconstruction and tectonic setting are still controversial. Based on the spatial distribution, stratigraphy and sedimentary sequence, sedimentary environment and sedimentary facies of the Ediacaran diamictites in northern China, combined with previous literatures at home and abroad, the above issues related to Ediacaran glaciations are systematically analyzed. This paper revealed that during the Ediacaran, there should have been a glaciation of younger than 580 Ma (Gaskiers)all over the world. The age constraints of the Ediacaran glaciations in northern China were placed between 562. 5 Ma and 551 Ma, and the subglacial, periglacial, and proglacial sedimentary facies can be identified; these form the diamictite from subglacial to proglacial, followed by normal marine sedimentary sequences vertically (in ascending order), in line with the sedimentary response pattern of continental glacier (ice sheet). The Ediacaran diamictites and glacial erosional forms are widespread distributed globally, and the cap dolostones can be developed above the diamictites, exhibiting sedimentary structures similar to the Cryogenian cap dolostones, but the carbon isotope characteristics of them are not the same. This paper speculates that the Proto- Tethys Ocean and its surrounding continents may have developed continental ice sheets during the Ediacaran, but there was no affinity between the Asian blocks and the Gondwana supercontinent. The results provide geological evidences for the global paleogeographic reconstruction and tectonic setting restore of the Ediacaran period.
