Early Cretaceous Palynological Assemblage and Its Environmental Significance in the Sediments of Liupanshan Group (Sikouzi Section), Liupanshan Region, Central China
摘要
The palynological study of 11 samplles from Lower Cretaceous Liupanshan Group on the Sikouzi section (spanning 116~103 Ma), Liupanshan Basin was carried out. 55 species (45 genera) of spore and pollen are detected. The palynoflora indicates that the climate in the Liupanshan area is hot and dry, and the palaeogeography is characterized by complex and various outlook during the late Early Cretaceous. The trend of climate change recorded by the pollen assemblages coincide with the global sea surface temperature fluctuation.
