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.
