摘要
以华北地台59处创面全涵盖式研究为基础，建立了华北石炭、二叠纪类生物群演化系列，并划分为6带13亚带，从中抽取4个与煤层生成关系密切的阶段加以详细讨论，分别称为：（1）Pr阶段；（2）T阶段；（3）Ps阶段和（4）S阶段。其中第1阶段反映煤盆地的构造启动，另外3个阶段分别代表太原组底部厚煤层、山西组主煤层、南华北区大风口组煤层的生成机制。
Form the detailed researh of 59 colunun sections in the North China Platform, thefusulinids bioane evoution series of the Permo-Carboniferous are set up, which can be dividedinto 6 anes including 13 subsones. Four zones with close relationship to the coalbed-forming areselected and discussed in this paper, they are named (1) Pr Stage; (2) T Stage; (3) Ps Stageand (4) S Stage. The first stage implicates the stat of the tectonics of the basin, and the otherthree stage explain the forming mechanism of the thick anlbed under the limetones of theTaiyuan Formation, the man anlbed of the Shanxi Formation and the coalbeds of the Dafengkou Formation in Southern North China respectively.
