摘要
概述了石炭-二叠系界线在世界、中国和新疆地区的演变,按国际委员会批准的牙形石Streptoynathodusisolatus的首现位置作为二叠系底界的标准,重新标定了塔里木盆地周缘柯坪地层小区、铁克里克地层分区、阿尔金山地层分区、巴楚地层小区以及塔中隆起、轮南低凸起、满加尔凹陷、和田河以东、且末断隆以北至轮南低凸起的广大沙漠覆盖区的石炭-二叠系界线,并对下二叠统有关化石带、阶的对比进行了评述。
Evolution of dividing lines of Carboniferous,Permian (C-P) in domestic areas(mainly in Xinjiang region) and other places around the world are outlined. Based on the standard of Permian bottom boundary for first,discovered horizons of streptoynathodus isolatus approved by the international committee,C-P dividing lines in such areas surrounding Tarim basin are re,calibrated as Keping subarea,Tekerik subregion,Arkin subregion,Bachu subarea,as well as Tazhong uplift,Lunnan low swell,Manjar seg and vast desert areal coverage in east of Hetian river,north of Qiemo faulted uplift to Lunnan low swell. The correlation of fossil beds and stages of Lower Permian is also reviewed in this paper.
