本文对准噶尔盆地东部CS-1井1 082—1 126m井段10块样品中所含孢粉和大孢子化石进行了比较系统的分析研究,共获得孢粉化石68属114种,以及少量大孢子化石,并建立Limatulasporites fossulatus-Klausipollenites schaubergeri孢粉组合,组合以Limatulasporites fossulatus和Kraeuselisporites spinullous比较发育,并见有Klausipollenites schaubergeri,Lundbladispora和Welwitschipollenites clarus等为主要特征。根据孢粉组合特征和大孢子化石的分布规律,详细讨论了含化石井段地层的时代及层位,认为该段地层的时代为晚二叠世晚期至早三叠世早期,层位为锅底坑组。
In this paper, we systematically analyzed and analyzed the sporopollen and megaspore fossils contained in 10 samples of well 1082-1126m from the CS-1 well in the eastern Junggar Basin. A total of 114 species of 68 genera of sporopollen fossils, as well as a few megaspores Fossils, and the sporopollen assemblage of Limatulasporites fossulatus-Klausipollenites schaubergeri was established. The combination of Limatulasporites fossulatus and Kraeuselisporites spinullous was developed, and Klausipollenites schaubergeri, Lundbladispora and Welwitschipollenites clarus were the main characteristics. Based on the characteristics of sporopollen assemblages and the distribution of megaspores, the ages and stratigraphy of the fossils containing fossil intervals are discussed in detail. The strata of the segment are dated from Late Late Permian to early Early Triassic, Pit group.
