The Nanhua Basin of South China recorded complete Cryogenian stratigraphic sequence from the Sturtian Glaciation (~717–660 Ma) to Marinoan (~654–635 Ma). interglacial Datangpo Fm in is divided into two members, and first member consists Mn-carbonate unit overlying black shale unit, containing a series large superlarge manganese deposits. metallogenic process deposits not clear, Mn-carbonates formed through precursor Mn-oxide/oxyhydroxide reduction or directly precipitated an anoxic water column. Moreover, redox conditions deep during precipitation are also controversial. In this study, high-resolution nitrogen contents (TN), isotope compositions, carbon compositions organic inorganic matter analyzed. δ 15 N values (+1.53‰ +5.26‰, mean +3.36‰) higher than those (−3.74‰ +3.54‰, +0.89‰). Mn show negative relationship with TN but positive implying that formation related variations. relatively indicated oxic conditions, NH 4 + can be released partially oxidized mineralization matter, resulting residual N-enriched being transferred clay minerals. Meanwhile, lower which primary signals. characterized by 13 C carb (−11.17‰ −5.22‰, −8.30‰), org , contents, excursions were degradation formation. findings study metallogenesis was constrained mainly interval basin. cycling provide new insights geochemical after Glaciation.
