Abstract The Santonggoubei manganese deposit is a recently found marine sedimentary manganese deposit in south tectonic zone of the eastern Kunlun orogen. Preliminary studies indicate that this manganese deposit is hosted in siliceous and fine-grained clastic rocks of the Ordovician-Silurian Nachitai Group. To date,the Santonggoubei deposit is only moderately studied with respect to sedimentary facies and depositional environment. Based on field investigations of regional geology and deposit geology,combined with sedimentological measurement of outcrop sections,petrographic observations and geochemical analysis,the authors suggest that the Santonggoubei manganese deposit formed on a passive continental margin. The main ore belts(from Ⅰ to Ⅲ)formed in the marginal facies of the southern deep-water basin,which was characterized by siliceous rocks,siliceous mudstone,and carbonaceous mudstone,intercalated with argillaceous siltstone;the marginal facies was in contact with slope sandstone and shelf sandstone-siltstone. The Ⅳ-Ⅴ mineralization belt was distributed in the restricted depression of the shelf facies,which was characterized by argillaceous siltstone,siliceous mudstone,and siliceous rocks. The Mn ore-bearing succession was overlain by shelf siltstone-fine sandstone and carbonate rocks. Overall,the palaeogeographic environments of the Santonggoubei manganese deposit were marine shelf depression and the margin of the deep-water basin. Geochemical analysis demonstrates that the formation of the main ore belt was closely related to the oxic-rich conditions of the basin waters. The precipitation mechanism of manganese is related to the episodic intrusions of shallow,oxygen-rich waters into the edge of deep-water basin.
