| 摘 要： | 通过对山东新汶煤田太原组底部徐家庄灰岩发育的有孔虫动物群和牙形石动物群的分析,鉴定出虫筳类有孔虫化石6属14种,非虫筳有孔虫7属16种,牙形石6属10种,建立一个有孔虫组合:Fusulinella-Fusulina组合;一个牙形石组合:Idiognathodusmagnificus-Streptognathodusparvus组合,通过与华北地区的生物群对比分析,太原组底部徐家庄灰岩中的生物群时代为晚石炭世中晚期。

| Abstract: | Through analysis on foraminifera and conodont fauna in Xujiazhuang limestone at the bottom of Taiyuan Formation in Xinwen coalfield in Shandong Province, it is determined that 14 species of foraminifera belong to 6 genera, 16 species of foraminifera belong to 7 genera, and 10 species of conodonts belong to 6 genera. A fusulinellafusulina assemblage and a conodont assemblage: idognathodus gnificusstreptognathodus parvus are identified. The age of the biota in Xujiazhuang limestone at the bottom of Taiyuan formation is middle late Carboniferous. |
