摘要/Abstract

摘要： “白垩纪大洋红层”（CORB）自20世纪末正式提出后已经迅速成为白垩纪新的研究方向之一。本文在参考国外CORB的学术研究成果基础上，重点对我们在西藏南部和意大利中部两个研究程度较高地区所获得的立典研究成果予以详细介绍，同时对CORB的全球性对比进行总结和归纳，对大洋红层蕴涵的古海洋、古气候信息进行详细评述。我们认为，CORB是沉积物在原地氧化条件下的产物，导致该氧化条件出现的主要因素是底层水高含量的溶解氧，而深层古洋流的发育很可能是导致高溶解氧含量的主要原因。

Abstract: The Cretaceous Oceanic Red Beds (CORB) has become one of hot topics since it was put forward and initiated by Chinese scholars during latest 1990s. This paper try to overview scientific results, especially from our groups, related to the CORB studying. The geological and geochemical characters of the CORB from both southern Tibet, Eastern Tethys Ocean, and central Italy, Western Tethys were introduced in detail. Based on global correlation, the characters and occurrences of the CORB were discussed. We also discussed the implications of the CORB related to the response of the paleoceanographic and paleoclimatic changes. We believe that CORB is deposited in highly oxic environment with high content of dissolved oxygen of deeper water, which the latter may be the result of changes in the location and formation of deep water and changes in ocean circulation.
