Oceanic Anoxic Events (OAEs) occurred during Aptian Albian, Cenomanian Turonian boundary and Coniacian Santonian, namely the OAE1, 2 and 3, with the OAE1 being further divided as OAE1a, 1b, 1c and 1d. But only the OAE1a and OAE2 reached to a global scale with others being limited in the Atlantic and Tethyal realm. Cretaceous OAEs usually corresponded to the positive excursion of carbon stable isotope in the marine carbonates, rapid turnover of marine biota and large scale distribution of organic carbon enriched black shales, which indicated wide ranges of changes in paleoenvironment and paleoclimate. Though the genesis of each OAE was somehow different, it is usually thought that Cretaceous OAEs may have been related to the igneous activities from the Large Igneous Provinces (LIPs).
