摘要
本文研究了华北聚煤区13条剖面的孢粉资料,划分了七个组合带,建立了石炭、二叠纪孢粉生物地层序列。根据孢粉组合发育特征的分析,认为石炭、二叠系界线应置于第Ⅱ组合带与第Ⅲ组合带之间。
After studied sporopollen inforniation from 13 sections in North China coal ac-cumulation area,a Permo-Carboniferous sporopollen biostratigraphic succession has beenworked out by the author.According to the development features of sporopollen assemblages,the Permo-Car-boniferous boundary was put between the 2nd assemblage zone and the 3rd assemblage zone.
