【摘要】 <正>山西晚石炭世地层发育良好,分布广泛,■类化石丰富。1927年,李四光教授在研究了我国北方石炭纪的■类之后,曾发表《中国北部之■科》之专著,为我国北方石炭纪■类研究工作的开展及地层的划分对比,奠定了重要基础。其后,区内的■类则缺乏更为系统的研究;特别是山西石炭系二迭系之分界,即山西组的时代归属问题,更是久有争议,悬
【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.
