miniferal integrated biostratigrapby of Ukhrul Ophiolite
complex, Manipur
A draft manuscript on Campanion-Maastrichtian coccolithlglobotruncanid biostratigraphy
of pelagic limestones from accretionary prism of Manipur, north-eastern India
has been completed. Tectonostratigrapllic frame-work of Manipur accretionary prism, based
on the recovery of globotruncanid/coccolith species from low latitude pelagic facies of
convergent plate margin, would serve as a type section for biostratigraphy and recognising
Campanian/Maastrichtian boundary in the Indo-Pacille region.

Two proljles, one each from Lamayuru (Ladakh) and BhowaJi (Kumaon) have been
undertaken for Quaternary pollen analysis. Fourteen samples from Bhowali section were
found devoid of spore/pollen contents.
Fifteen samples [j'om more than 110m Lamayuru section covering time span of
Weichselian have been macerated for pollen analysis. Out of these, five samples have been
found to be barren while others are represented mostly by Picea and Abies which were
