摘要: 赣东北白垩纪地层单位涵义一直较为混乱,本文从事件沉积入手,确定了4种不同类型的界面。笔者根据其事件沉积界面,划分出3个组一级和两个段一级的岩石地层单位,较好地控制了陆相地层的纵向和横向的突变,而且对深入盆地研究,解决年代地层都具重要作用。

Abstract: The division of the Cretaceous strata in northeastern Jiangxi has been highly muddled for the long time. Four types of the bounding surfaces of the Cretaceous event deposits are redivided in this study, including three formation-scale and two member-scale lithostratigraphic units. Each of the lithostratigraphic units is interpreted to be the response of sedimentation to the specific events during the distinct phases of initiation, development and termination of the basin, and constrained all the time by the palaeoclimates in the study area.
