新疆准噶尔盆地东部覆盖区锅底坑组的发现及其化石证据
|
摘要
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。
Abundant spore-pollen were discovered from the Guodikeng Formation in Well CS-1 of the eastern Junggar Basin,Xinjiang,NW China.They were assigned to 114 species in 68 genera and 3 genera of megaspore.According to the abundance of the important species,the present palynoflora was named the Limatulasporites fossulatus-Klausipollenites schaubergeri Assemblage.Based on the correlation among the known Permian-Triassic assemblages,the author considers the Guodikeng Formation to be late Late Permian to early Early Triassic in age.
