Permian paleogeography of Peninsular and Himalayan India and the relationship with the Tethyan region in Gondwana Five. Selected papers and abstracts of papers.
During the Permian, Peninsular India, the Lesser and Himalayan India and southern Tibet are considered to have formed a single block or plate.

Structure and tectonics of Gondwana basins of peninsular India in Gondwana Five. Selected papers and abstracts of papers.
The intracratonic Gondwana basins of peninsular India occur in long, narrow, well-defined belts on the Precambrian platform, corresponding to rivervalleys of Damodar-Son, Mahanadi and Godavari. The basins are half grabens or grabens, with margin

While Greater Antarctica remained continental throughout Mesozoic time, the Antarctic Peninsula was partly covered by sea. Present data suggest that the break-up of Gondwana was initiated in the Middle to data Jurassic with the first significant
lateral movements in the Early Cretaceous. During this period, the Antarctic Peninsula area occupied an important paleogeographical position, near the junction of major new seaways that were opening between South America and Africa, along the eastern coast
of Africa, and between India and the Antarctic-Australasian block. The biogeographical affinities of ammonite faunas in the Antarctic Peninsula are briefly reviewed in the light of these changing paleogeographical conditions.

sediments. The sea encroached and widened from the Indo-Australian Gulf in early Jurassic times. The formation is classified here as a distinct marine unit in the Upper Gondwana formations of peninsular India.

with each other and probably with South America, may have provided a passage for the migration of early marsupials until well into Eocene time. Peninsular India may have been connected to Africa until very late Cretaceous time.
