- •
Two different facies can be identified in the upper Permian of Meishan section.
- •
These two different facies represent anoxic and oxic conditions respectively.
- •
Our study indicates a long period of oxygenation after the end-Permian extinction.
- •
The δ13C negative excursion appears to have no relation with the redox change.
