Upper Bhander Sandstone: An Example of Barrier Beach Deposits from Tantpur area, District Agra, Uttar Pradesh, India

Abstract

The Upper Bhander Sandstone occurring in the Tantpur area consists of red, brown and dirty white orthoquartzite with intercalations of shales. The sandstone is texturally and mineralogically mature. The palaeocurrent pattern worked out with the help of primary sedimentary structures reveals that the direction of the sediment transport remained north-westerly. The coarsening upward of the sequence, sedimentary structures, elongated sand bodies and polymodal palaeocurrent pattern indicate that Upper Bhander sandstone sequence of the Tantpur area was deposited on a beach complex in a regressive shoreface environment.
