| Abstract: | The present paper deals with sporopollen assemblage of the Early Cretaceous XiagouFm.and Zhonggou Fm.from the Hanxia Goukou section of Yumen in Gansu,NW China.This assemblage contains3 7genera and53 species of spores and pollen and2 species of2genera of fossil algae.According to the abundance of the important genera,the presentsporopollen flora was named the Cicatricosisporites-Schizaeoisporites-Classopollis-Jiaohepol-lis Assemblage.Characteristics of this sporopollen assemblage are as follows |
