Lithostratigraphy of the Paleogene Shelf Sediments in Assam and Meghalaya – A Review

R.K. Sarmah and R. Borgohain

DOI : 10.9780/22307850, Published By : Laxmi Book Publication

Abstract :

The Paleogene Shelf sediment are well developed in Garo hills, Khasi and Jiantia hills along the southern margins of Shillong Plateau in Meghalaya, parts of Mikir and North Cachar hills of Assam and also in the subcrops of Dhansiri and Upper Assam valleys. These sediments represent diverse depositional environments from marine, lagoonal, tidal flat to fluvio–deltaic exhibiting the effects of differential tectonic movements in basin floors,changes in shorelines, sediment source and varying degree of energy conditions of thetransporting media. As a consequence, certain problems may be encountered in erecting a unified scheme of generalized stratigraphic columns for the entire region under review. The stratigraphic study of these lithounits would obviously help to understand the diverse and subtle variations in lithofacies of the Paleogene sequence in different areas of basin positions.
