摘要
陆地系统是地球表层系统的重要组成部分,国际上因为缺少系统的陆相白垩纪地质记录,使得中国的陆相白垩纪地层得到了极大的关注。近十余年来,中国陆相白垩系地层学研究发展迅速,但是新的、系统的陆相白垩系地层对比成果一直缺位,这使得不同学者对中国陆相白垩系的认识存在偏差,造成诸多不必要的争论及不便。本文在收集整理前人白垩纪陆相地层对比成果的基础上,补充近十余年来火山岩年代地层学、古生物地层学及磁性地层学资料,对中国陆相白垩纪地层进行了重新对比,旨在为中国陆相白垩系研究提供系统的年代地层框架。
Terrestrial system is an important part of earth surface system. Limited distribution made terrestrial strata in China be hot spot. Thousands of Cretaceous terrestrial stratigraphic researches had been done in last ten years. But, there was an absence of a new systematic stratigraphic correlation, which made different recognitions in Cretaceous terrestrial strata in China and important geological event worldwide. Based on former researches, a new stratigraphic framework which includes many new lava ages, biostratigraphic and magnetostratigraphic evidences is established. Purpose of this paper is to prove a systemic stratigraphic correlation for future researches.
