The Petrogenesis of the Lower Rewa Sandstone, Karauli State, Rajasthan

The Lower Rewa Sandstone is medium to fine grained, moderate to well sorted, mature, symmetrical to positively skewed, mesokurtic to leptokurtic, quartz-arenite. Ripple marks are present whereas cross-stratifications are not common. Vector analysis indicates a north-westerly palaeocurrent direction. From the study of the petrological characters, elongation quotient of the quartz grains, C-M pattern distribution of the quartz grains and palaeocurrent azimuthal pattern, a beach environment of deposition with a steady supply of sediments from a granitic source area is postulated.
