- •
Comparative Fe-S-C study was conducted on O-S transitional strata in South China.
- •
Strong spatial heterogeneity of oceanic redox evolution was observed between sites.
- •
Large perturbation of the carbon and sulfur cycle was observed for study sections.
- •
A dual-control involving Hirnantian glaciation and Kwangsian Orogeny is proposed.
