| Abstract: | The continental strata of Mesozoic are well developed in Baicheng area of sou-thern Xinjiang. Relatively abundant spores and pollen were obtained in Ahe.Yen-gisar and Kezilenur Formations, 58 genera and 93 species were identified, including 2 new species and 2 new combination species.
There are spores and pollen in Ahe Formation, in the sporopollen assemblage, pteridophytic spores are richer than gymnospermous pollen and contain a few arc-ritarcha. This assemblage belongs to the late stage of Late Triassic. In the sporo-pollen assemblage of Yengisar Formation, the gemnospermous pollen is richer than pteridophitic spores, also containing a few arcritarcha. This assemblage belongs to Early Triassic. Rich microspores have been discovered in Kezilenur Formation. The sporpollen assemblage is predominated by gymospermous pollen, with less pteridophytic spores. The age of the assemblage should be assigned to Middle Jurassic. |
