Ib. Singh et al., POINT-BAR COMPLEX OF AN EXHUMED CHANNEL IN UPLAND INTERFLUVE OF THE GANGA PLAIN, INDIA, Journal of the Geological Society of India, 51(3), 1998, pp. 315-322
Facies architecture and evolutionary history of a point bar complex of
exhumed channel on the upland interfluve surface of the Ganga Plain i
s presented. The point bar complex is made up of four distinctive sequ
ences, each characterized by a specific lithofacies association and gr
ain size, where successive sequence shows decrease in grain size and r
educed channel width denoting reduction in the discharge of the channe
l. The top of each sequence represents a hiatus surface marked by dens
e bioturbation. The flow in the exhumed channel was towards south and
southwest. At the end of the deposition of third sequence neotectonic
activity caused uplift, tilting of the surface and disruption of the r
iver channel. A facies model of such deposits is proposed.
