Memoirs of the Geological Survey of India the Economic Geology and Mineral Resources of Bihar Province

1942

We may therefore accept the original level of the 'pre-Tertiary peneplain as being rather lower than the present level of the base of the lavas along the western scarp of the Rajmahal hills. [...] Along the northern side however the tendency west of the Rajmahal hills has been towards a steepening of the tilt culminating in the sharp warp represented by the fall in elevation from Kodarma to the plains of Gaya and this characteristic continues across to the scarp face of the Kaimur plateau. [...] The movement still persists in the form of a gradual rise of the whole landmass south of the Gangetic alluvium: Examining broadly these Tertiary to Recent movements in the whole of Bihar we note that there has been a definite subsidence to the north and northeast in the region of the Ganges. [...] In the eastern part of the Santa! Parganas the Rajmahal trapa overlie the Gondwana sediments which fringe the western edge of the lavas but to the east the latter slope below the Gangetic alluvium. [...] It is apparent that over the greater part of the Gangetic plains the intake of the deep-seated water-bearing strata is not the immediate surface but is closer to the edge of the alluvium and much of the water has travelled underground from as far afield as the United Provinces and the Punjab.
