摘要
In continental basins, base level and sequence stratigraphy is controlled by tectonic movement, climate, and sediment supply. Climate is also a major controlling factor on vegetation and palynological assemblage. Thus, sequence stratigraphy and palynological assemblages may be related. This study focuses on the palynology and sequence stratigraphy of the Paleogene successions in the Jiyang Depression. Paleogene climate was reconstructed using palynological data. The palynological data was also correlated with sequence stratigraphic data from one first-order, four second-order, and ten third-order sequences. This study shows that palynological data can be used in sequence stratigraphic division of Paleogene successions in the Jiyang Depression.
