　　The Cretaceous is an important period in which occurred many geological events,especially the OAEs (Oceanic Anoxic Events) characterized by black shales,and the oxic process characterized by CORBs (Cretaceous Oceanic Red Beds).This paper describes the causative mechanism which explains how the oceanic environment changed from anoxic to oxic in Cretaceous.
