- •
Ediacaran Doushantuo phosphatic rocks from Zhangcunping section in South China are studied.
- •
Carbonate fractions show seawater-like REE patterns and super-chondritic Y/Ho ratios.
- •
Phosphate fractions display hat-shaped REE patterns and low Y/Ho ratios, recording diagenetic fluid features.
- •
Anoxic environments are indicated for Ediacaran Doushantuo ocean in South China.
