湖南汝城盆地原定中侏罗世地层发现早白垩世孢粉组合
The discovery of Early Cretaceous spore-pollen assemblage in the Middle Jurassic strata of the Rucheng Basin, Hunan Province
摘要
Abstract
The Lijiadong reservoir section of the Rucheng Basin in Hunan Province was originally considered to be of Middle Juras⁃sic. Based on the analyses of 28 samples of spore-pollen collected from this section, the authors found abundant spore-pollen fossils from 24 of the samples. Among these fossils, the taxan Cicatricosisporites is most abundant, while the taxa Hsuisporites, Pilosisporites, Aequitriradites, Erlianpollis, Appendicisporites and Parvisaccites are highly abundant. In addition, a small number of angiosperm pol⁃lens were found in the sample. This fossil assemblage shows typical Early Cretaceous features. It is thus held that the geological age of Lijiadong reservoir section should be Early Cretaceous rather than Middle Jurassic.关键词
