Late Cretaceous red chalk units of “deep” marine origin were recognised and published from the North Sea Basin almost thirty years ago (King et al., 1989), however it is only now that we are beginning to recognise their oceanographic, depositional and climatic significance. Their stratigraphic occurrence is redefined and an additional red unit is proposed. The palaeoceanographic implications of these red units are considered in the light of recent studies on the origins and occurrences of Cretaceous Oceanic Red Beds (CORB’s) and of the red horizons in the onshore Cretaceous Chalk of North West Europe.

简要回顾北海近海地区的晚白垩世“海洋红层”

大约三十年前，北海盆地已经认识并发布了“白垩纪”深海起源的晚白垩世红色粉笔单元（King等，1989），但是直到现在我们才开始认识到它们的海洋学，沉积学和气候学。意义。重新定义了它们的地层学意义，并提出了一个额外的红色单元。根据近期对白垩纪海洋红层（CORB）的起源和发生以及西北欧陆上白垩纪粉笔的红色层位的研究，考虑了这些红色单元的古海洋学意义。
