- •
Redox variations and OM accumulation on the Yangtze carbonate platform during the E-C transition were studied.
- •
A sulfidic condition spread onto the Yangtze carbonate platform interior during the late Cambrian Stage 2.
- •
Local and widespread phosphogenesis occurred during the Late Ediacaran to earliest Cambrian.
- •
OM accumulations of Early Cambrian shales were in connection with persistently anoxic conditions and intermittent replenishment of recycled organic P to surface waters.
