Abstract

Selected samples from the intertrappean beds of Abor Volcanics were macerated for palynofossils in an attempt to provide fossil evidence for their age, The palyno-fossils so far isolated are trilete and monolete microspores, radial monosaccates and striated as well as non-striated disaccate pollen of Early Permian age. The fossil evi· dence suggests similar age to the intertrappean beds and lead to the conclusion that the Abor Volcanics of the studied area viz., Yinkiong, Dalbuing and Mariyong of Dihang valley (Arunachal Pradesh) are of Early Permian age.
