| Abstract: | The spores and pollen assemblage was obtained from the core samples of the bore in Zhuxuanzhung,Xiu county,Anhui province.The characters of assemblage are that the pollen of gymnosperm make up absolute predominance, content of pterido-phytic spores are very low.The main species listed below: classopollis parvus,C.annu-lates,C.classoides,C. reticulates,Cycadopites nitidus,C. typicus,C. subgranulatus, Monosu-Icites sp.podocarpidites paulus,P.queenslandi,pinuspollenites sp,piceaepollenites exiho-ides ,P. complanatiformis, Quadrculina limbata, Q. anellaef ormis, Q. enigmata, Ephedripites fusiformis,E.rotuntus, Inaperturopollenites sp, Cyathidites minor, Lygodiumsporites, etc.The character of palynologycal assemblage reflect that stratum age belonging to late Jurassic |
