Surface and subsurface evidence of neotectonics and the aquifer disposition in central gangetic alluvial terrain of Kanpur-Unnao region in Uttar Pradesh, India

Abstract

Both surface and subsurface evidences exist along the longitudinal section of the Ganga river in Kanpur-Unnao region of Central Ganga Plain indicating the effect of tectonic subsidence. While the surface evidences are discontinuous chain of high uplands with escarpments on the southern bank of the Ganga river and the wide flood plain on the northern side, the subsurface evidences are in terms of sudden deepending of the granitic basement towards north followed by deposition of coarse sand and gravel forming thick aquifers in the close vicinity of present channel of the Ganga river. The petrological examination of the aquifer material also indicates that the material has been derived from a deformation zone.
