... ). The Semri Group represents a cyclic sedimentation of rudaceous, arenaceous, argillaceous and carbonate formations ( Table 1 ). This group has largely developed as a result of rifting followed by sagging processes ( Bose et al., 2001 ) and it contains evidences of tectonically-induced seismicity in the Son...

The Deoland Formation is the lowermost unit of Semri Group dominated by conglomerate and sandstone (Chakraborty and Bhattacharyya, 1996; Bose et al., 2001). The Arangi shale overlies Deoland Formation and present only in Son valley. It consists mainly of grey shale...
