STRATIGRAPHY OF BARAIL GROUP OF SEDIMENTS EXPOSED ALONG NH-44 ROAD SECTION FROM JOWAI TO BADARPUR, NE INDIA

Abstract

In India the tertiary group of sediments has consists of vast deposits of shale, sandstone, coal, limestone, which reflects the different environmental condition of that time period. The tertiary group of rock has been exposed in regions like Assam region, Jammu- Kashmir, Simla- Garhwal, and western Rajasthan, along coastal tract of Gujarat etc. The variety of tertiary deposits in accordance to their depositional environment provide important clue to fossil fuel exploration and coal lignite deposits. This have found wide in Gujarat, Rajasthan, Assam -Meghalaya region which have high economic and social value. In this context the present work is an approach to develop the paleoenvironmental reconstruction of Assam- Meghalaya region within the Jowai-Badarpur road section comprising Oligocene age based on lithostratigraphy and palynofacies analysis.
