4 Chronostratigraphy
Optically Stimulated Luminescence (OSL) dating of 17 samples (Table 2) was carried out on samples collected from fluvial sediments representing distinct sediment

well archived as staircases of fluvial terraces running parallel to present day chanFig. 16 Valley morphology, disposition of terraces, lithologs of measured sections and sedimentary facies of terrace deposit at Purola road (right bank section)
