“…The geological setting, as discussed in section 2.1 of this paper, indicates that the continental basins of the Indian part of Gondwana, including the Raniganj basin, were tectonically active during PermianTriassic sedimentation, and there is direct evidence for episodic movement along basin boundary and intra-basinal faults during that time (Ghosh 2002). This indicates that recurrent syn-sedimenatry seismic activity occurred during the Permian-Triassic Page andSuppe (1981), Mills (1983) Large-scale water movements Siegenthaler et al (1987) Lateral facies variations, and high proportion fine grain sediment and water McDonald and Shilts (1975), Chunga et al (2007), content in sediments in glacial environments Gruszka andVan Loon (2007), Van Loon (2009) Seismic shaking Field et al (1982), Bhattacharya and Bandyopadhyay (1998), Shiki et al (2000), Schnellmann et al (2002), Spalluto et al (2007), Aboumaria et al (2009) Convolute lamination Fluidization-liquefaction events and concomitant expulsion of pore water Middleton and Hampton (1973), Allen (1977), due to earthquake or occasional pounding of channel-base sediments Chakraborty (1977), Cojan and Thiry (1992), Owen by large wave during fluvial processes (1996), Rossetti (1999), Samaila et al (2006) Convolute laminae having intact tops of the domes while sandwich...…”
