Abstract

The palynological assemblages comprising angiospermous pollen, pteridophytic spores, fungal remains, gymnospermous pollen, dinoflagellate cysts, acritarchs and reworked Permian spores and pollen have been reported from Siwalik sediments exposed in Kameng, Subansiri and Siang districts, Arunachal Pradesh. Palynological comparison with extant plants has been attempted to determine the palaeo-vegetation, Palaeoclimate and environment of deposition. Geological history and palaeogeography of Neogene sediments of Arunachal Himalaya have been discussed.
