Paleocene-Eocene Palynostratigraphy of the Northern Margin of Upper Assam Basin, India
Abstract—The palynofloral assemblage of a 3976 m deep well of Barekuri area, Northern part of Upper Assam Basin, India is studied. The study is confined to the 636 m thick Paleocene - Eocene sequence comprised of Langpar, Lakadong + Therria, Nurpuh, Prang and Kopili formations. The dinoflagellates and pollen grains of Palmae family belonging to genus Neocouperipollis together with the reported foraminifera from the neighbouring region indicate shallow marine condition/near shore environment during the deposition of the entire Upper Paleocene-Eocene sediments. The good representation of the Pteridophytic grains suggests prevalence of humid tropical climate at the time of deposition. The complete absence of marine elements after the deposition of Kopili Formation is indicative of regression of sea at the end of Eocene.
