新疆巴里坤地区石炭纪孢粉化石的发现及其古气候演化
Carboniferous palynological fossil evidence and its implications for paleoclimatic evolution in Barkol area,Xinjiang
摘要
Abstract
[Objective]This study investigates the Carboniferous Yaomoliang Formation in the Moqinwula Mountains,northern Barkol County,Hami,Xinjiang,with the aim of refining stratigraphic age constraints and reconstructing the associated paleoclimatic conditions.[Methods]By processing and identifying the collected palynological fossils and establishing palynological assemblages,than to restore the background of ancient plant communities and explore the paleoclimatic characteristics of the research area.[Results]Based on fossil assemblages,stratigraphic distribution,and regional correlation,a spore-pollen assemblage of Cyclogranisporites aureus-Protohaploxypinus horizontatis(AH)was established,indicating a middle Bashkirian age in the Late Carboniferous.[Conclusions]The spore-pollen assemblage reveals a floristic composition distinct from both the Euramerican-Cathaysian and Angara floras,but broadly consistent with the Subangaran flora proposed by previous results.Accordingly,the study area is assigned to the Subangaran floral subprovince during the Late Carboniferous.关键词
