Keywords:Lithostratigraphy, Tertiary sediments, Jaintia Hills, Cachar (India)
The paper includes the field observations on the sediments along Jowai-Badarpur Road section in Jaintia Hills and Cachar, depicting their lithostratigraphy. Starting from Jowai towards Badarpur various Tertiary sediments were observed. In ascending order, these are Therria, Sylhet Limestone, Kopili, Laisong, Jenam, Renji, Bhuban, Bokabil, Tipam Sandstone and Recent alluvia. The lithology, nature and location of contacts and fossil contents of each of these formations are discussed.
At Sonapur, 76 km from Jowai, the section is crossed by the Dauki Tear Fault, which separates the Palaeocene-Eocene rocks of the shelf facies to the north from the Oligocene-Miocene rocks of the geosynclinal facies to the south.
