摘要:

通过对华北地台早石炭世晚期至早二叠世腕足动物群的全面系统研究,认为全区腕足动物群的发展演化具有一致性和阶段性,可清楚地分为5个阶段,即田师傅期(C13—C21)、本溪期(C22)、太原期早期(C23)、太原期晚期(P11)和山西期(P12)。在此基础上,进行了国内外同期腕足动物群的对比和腕足动物生物古地理分析,确立了华北地台东北部田师傅期腕足动物的生物地理归属,命名为天山—辽吉腕足动物生物地理分区,同时阐明了研究区内晚石炭世晚期至早二叠世腕足动物生物地理区划特征。

Abstract:

  A systematic research on the late Early Carboniferous to Early Permian Brachiopods in the North China Platform shows that the evolution of the Brachiopod faunas have consistent regional characteristics. A total of 5 evolution stages and 8 assemblage zones have been identified. Five stages include the Tianshifu stage (C13~C21), the Benxi stage(C22), the Early Taiyuan stage (C23), the Late Taiyuan stage (P11) and the Shanxi stage (P12), which consist of the 1st, the 2nd, the 3rd, the 4th7th, and the 8th assemblage zones, respectively. All of these assemblage zones in the North China Platform have been compared with contemporaneous faunas in other parts of the world. Besides, the Brachiopod biogeography of the late Late Carboniferous to Early Permian in the research area has also been expounded. A new Brachiopod subprovince, the TianshanLiaoji (LiaoningJilin) Brachiopod biogeographical subprovince, has been established to represent the distribution of the Tianshifu Brachiopods in the northeastern part of the North China Platform.
