| Late Cretaceous and syn-collisional sediments of Paleocene and Eocene in the Sub Himalaya, Lesser Himalaya and Shillong Plateau in Meghalaya are marine transgressive deposits. Sedimentological and paleoclimate studies across the Cretaceous-Tertiary boundary and Paleocene-Eocene thermal maxima are significant for understanding the origin and extent of the Tethys Sea and the evolution of the Himalayan-Alpine orogenic belt. |
