| Abstract: | The Dasheng Group in Shandong Province is made up of continental including pyroclastic rocks. The Schizaeoisporites Ephedripites Tricolpites(SET) Assemblage from the Dasheng Group is characterized by the dominance of Schizaeoisporites,Classopollis, Ephedripetes and Exesipollenites . The Bisacca pollengiains are rare. It is characterized by the abundant presence of early angiospermous pollen (10 per cent) mainly Tricolpites. The SET assemblage is assigned Cenomanian-Turonian in age. |
