Organic-rich shales are located at the lower part of Longmaxi Formation.
- •
Organic-rich shales were deposited in anoxic environment, while the organic-poor shales in oxic condition.
- •
Redox-sensitive elements proxies should be combined with sedimentary and biotic characteristics in study of paleo-redox condition.
