笔者多年来先后对江汉盆地、苏北盆地、华北盆地、南阳盆地、松辽盆地及安徽、河南、湖南等一些较小陆相盆地的晚白垩世、早第三纪介形类进行了一些研究,积累了不少资料。本文根据这些材料,并参考外单位的成果,对我国东部地区的白垩—第三纪介形类组合序列作了系统叙述,并对白垩—第三纪的地层界线做了初步讨论(见表1)。文中自下至上共叙述10个介形类化石组合,可供地质及古生物工作者参考。
Over the years, I have done some researches on the Late Cretaceous and Early Tertiary ostracods in Jianghan Basin, Subei Basin, North China Basin, Nanyang Basin, Songliao Basin and some minor continental basins in Anhui, Henan and Hunan , Accumulated a lot of information. Based on these materials and with reference to the achievements of the external units, this paper systematically describes the sequences of the Cretaceous-Tertiary Ostracoda in the eastern part of China and makes a preliminary discussion on the stratigraphic boundaries of the Cretaceous-Tertiary period (see Table 1 ). The article from the bottom up describes a total of 10 types of fossil assemblage for geology and paleontology workers reference.
