【Abstract】 The Upper Carboniferous,well developed in Shanxi(山西)Province,may be divided into the Jinci(晋祠),Taiyuan(太原)and Shanxi Formations proposed by Liu and Ying(1957).The boundary between the later two Formations was placed on the base of the Beichagou(北岔沟)Sandstone revised by Du (1958).Fusulinids are more abundant in every limestone of these Forma- tions,which consist of 20 genera,300 species,subspecies and varieties.The rapid evolution of these Fusulinids permits to set up biostratigraphic zona- tion of the system.Three zones and seven subzones are established in Table 1, and the comparison of the Late Carboniferous Fusulinid Zones in each re- gion of Shanxi in Table 2.The correlation between the Upper Carboniferous of Shanxi and same strata in inter-continental is given out in Table 3.更多还原
