甘肃灵台晚中新世—早更新世生物地层划分及其意义

郑绍华, 张兆群   

Abstract: Since the first discovery of mammalian fossils in 1964 from the Leijiahe area, Lingtai, Gansu, there have been three field teams working there on the "Leijiahe Formation", which developed on the Cretaceous limestone and before accumulation of the Loess. This Formation was thought to be of Pleistocene (Huang et al., 1979), Pliocene (Huang et al., 1993) and Late Miocene to Early Pleistocene (Zheng, 1994) respectively. In 1998— 1999, financed by the NSF we did more detailed biostratigraphic works on three sections, namely, Loc. 93001, 93002 and 72074(4) section (Zheng and Zhang, 2000; Zhang and Zheng, 2000, 2001). The present paper gives synthetic analysis with small mammals from the three sections and comparison with some faunas from North China.

摘要: 将甘肃灵台雷家河地区3个剖面按生物学和地层学原理综合成一个完整的生物地层剖面,并分成6个生物地层带:I+II带为保德期中晚期;III~IV带为榆社期;VI带为泥河湾期。探讨了华北各地方动物群在雷家河剖面中的相应位置。
