摘　　要：白垩纪期间出现过多次大洋缺氧事件与大洋富氧事件,其沉积记录分别对应于黑色页岩和大洋红层。文章在国内外学者前期工作的基础上,对国际上白垩纪大洋缺氧事件和大洋富氧事件的最新研究进展进行回顾与总结,主要包括黑色页岩和大洋红层的岩石特征与成因、大洋缺氧事件和大洋富氧事件形成机制及两者之间的关联,希望能够为理解和预测未来的全球气候环境变化提供借鉴和依据。Black shales and oceanic red beds, as the products of oceanic anoxic and oxic events, respectively, are common during the Cretaceous greenhouse world. We summarize the recent research progress of oceanic anoxic and oxic events including the characteristics and causes of Cretaceous black shales and oceanic red beds, and the formation mechanism of Cretaceous oceanic anoxic and oxic events. Then we discuss the relationship between these two events, hoping to provide the reference and basis for understanding and predicting the future global climate and environment changes.
