摘　　要：新汶煤田上石炭统太原组中共含有５层海相灰岩，各层灰岩中均含有较丰富的类化石。经作者研究，根据它们的属种组成和在纵向上的分布规律建立了两个带三个亚带：Ⅱ．Ｔｒｉｔｉｃｉｔｅｓｂｏｓｈａｎｅｎｓｉｓ带；Ⅰ．Ｐｓｅｕｄｏｓｃｈｗａｇｅｒｉｎａ带，此带又划分出三个亚带：３．Ｓｃｈｗａｇｅｒｉｎａｖａｌｉｄａ－Ｂｏｕｌｔｏｎｉａｓｉｍｐｌｉｃａｔａ亚带，２．Ｔｒｉｔｉｃｉｔｅｓｓｈａｎｄｏｎｇｅｎｓｉｓ－Ｍｏｎｔｉｐａｒｕｓｔｈｏｍｐｓｏｎｉａｎａｓ亚带，１．Ｓｃｈｗａｇｅｒｉｎａｅｌｋｏｅｎｓｉｓ亚带。对各带及亚带的类动物群特征进行了阐述，同时，对较低级的类动物群在层位上高于Ｐｓｅｕｄｏｓｃｈｗａｇｅｒｉｎａ带的现象进行了探讨。并将本区所建立的化石带与华北部分地区相应的组合带进行了对比。The Fusulinida fossil bearing in five limestones in Taiyuan Formation are very abundant in Xinwen coalfield.Based on the systematic study, the authors clossified the Fusulinid faunas into two zones and three subzones:the upper zone of Triticites boshanensis and the lower zone of Pseudoschwaerina which can also be classified into three subzones in descending order: subzone of Schwagerina valida-Boultonia simplicata,subzone of Triticites shandongensis-Montiparus thompsoniaus,subzone of Schwagerina elkoensis. The properties of these zones and subzones and the reasons why the zone of Triticites boshanensis distributed above the zone of Psendoschwagerina are expounded. The fossil zones of Fusulinid faunas in Taiyuan Formation of Xinwen Coalfield are compared with that of other regions in North China.
