- •
Three radiolarian zones were established, suggesting a Roadian to middle Captanian age for the Gufeng Formation;
- •
The Gufeng cherts deposited in northern and southern marginal basins of South China Craton have different sources;
- •
An increase in abundance of spherical radiolarians coincides with enhanced productivity in reducing conditions;
- •
Oceanic productivity controlled deposition of Middle Permian organic-enriched sediments;
- •
Surface ocean productivity influences redox condition of the bottom water.
