“…Similar to all other Gondwanan basins of Peninsular India, the Rewa Sub-basin is a fault-controlled half-graben-type basin along a NW-SE-oriented palaeosuture of the Son-Mahanadi Basin (Fig. 1a; Acharya, 2018; Banerjee et al 2020; Dasgupta, 2021). In the north, the Malwa Ridge separates the Rewa Sub-basin from the Son Basin (left side of the Malwa Ridge shown in Fig.…”

“…In India, Talchir sedimentary rocks (Late Carboniferous to Early Permian) deposited within fault-controlled half-graben-type basins along palaeosuture lineaments such as the Damodar Valley, Son-Mahanadi Basin and Satpura Basin (Banerjee et al 2020) bear diagnostic glaciogenic signatures (e.g. dropstones, glacial till deposits, glacial pavement, repeated glacial advance-retreat cycles with shifts in the palaeoshorelines during the Talchir sedimentation) related to Late Palaeozoic glaciation (Smith, 1963a, 1963b; Casshyap & Qidwai, 1974; Das & Sen, 1980; Casshyap & Tewari, 1982; Eyles & McCabe, 1989; Bose et al 1992; Mukhopadhyay & Bhattacharya, 1994; Veevers & Tewari, 1995; Bhattacharya et al 2004, 2005; Maejima et al 2004; Bhattacharya & Bhattacharya, 2006, 2010, 2012; Chakraborty & Ghosh, 2008 Varshney & Bhattacharya, 2023).…”

Among the vast swathes of Gondwanan sedimentary rocks in India, exposures of the Lower Permian Talchir Formation at Manendragarh in India are exceptional for their cold marine faunal assemblage and muddy conglomerates of possible glacial origin. They may represent a record of the late Palaeozoic glaciation that affected Gondwana in the Permo-Carboniferous. Although the fossil record is relatively well documented, the sedimentology of this area is not well understood. This paper intends to fill the gap in knowledge regarding palaeogeography and the palaeoenvironmental changes within the basin through space and time. We distinguish conglomerates that are formed by glacial and mass flow processes. The lateral variation in facies associations along a NNE-SSW transect in the study area identifies the depositional basin as an interior sea that formed when the sea spilled over a steep basement ridge during a transgression. The benthic organisms remained confined to the seaward basin margin where they only flourished in the initial stage of basin filling. Locally derived, bioclastic storm beds are limited to the seaward flank of the basin. Alternating phases of glaciation and interglaciation resulted in an interbedded succession of grey shales and interglacial density flow deposits. The channels that fed these density flows are preserved closest to the landward margin of the basin. Co-existence of glacial diamictites and interglacial density flow deposits highlights the climatic changes in this part of Gondwana during the Late Palaeozoic.

“…Most of the subcontinents of the supercontinent Gondwanaland were fully or partially submerged at different time intervals during the Late Cretaceous, which led to the formation of shallow epicontinental seas in certain areas. Evidence of Cretaceous sea-level rise in the Indian subcontinent is recorded within thick sedimentary successions of the Cauvery Basin (Nagendra et al 2011(Nagendra et al , 2013, Shillong Basin (Singh and Mishra 2000), Kutch Basin (Desai 2013), Bengal-Assam Basin, parts of the Himalayan fold belt, and the Narmada rift basin in west-central India (Acharya and Lahiri 1991;Banerjee et al 2020).…”

Rising sea-levels in tectonically active epicontinental basins often lead to varied depositional settings and palaeogeography, mostly influenced by the net accommodation resulting from mutual interference of the extent and nature of landward encroachment by the sea and the net sedimentation. The Cenomanian Nimar Sandstone Formation, Bagh Group, Narmada rift basin, uniquely portrays the effect of sea-level rise within an intra-cratonic setting and attributes to the corresponding palaeogeographic changes in west-central India. An integrated sedimentological–sequence-stratigraphic study of the broadly fining-upward Nimar Sandstone Formation (thickness ~ 20–30 m) depicts the actual nature of changeover from a fluvial to a marine-dominated transitional depositional setting. Detailed sedimentological study reveals total seventeen facies, grouped in five facies associations, viz., the channel-fill facies association (FA-1), the overbank facies association (FA-2), the fluvial-dominated fluvio-tidal facies association (FA-3), the tide-dominated fluvio-tidal facies association (FA-4), and the shoreface facies association (FA-5). Overall facies architecture indicates a west-to-eastward marine encroachment, resulting in stacking of three distinct palaeo-depositional conditions: (i) an initial fluvial system with channel and overbank, changing into a tide-influenced fluvial bay-head delta in the inner estuary, followed by (ii) marine encroachment leading to a tide-dominated central estuary with inter- to sub-tidal settings, and finally, (iii) with further intense marine encroachments, a wave-reworked open shore condition in the outer estuary zone. The overall fining-up succession with a systematic change from fluvial to marine-dominated depositional systems points to a landward shift of the shoreline, signifying a major transgressive event correlated to the Cenomanian global sea-level rise. Characteristic stratal stacking patterns point to four coarsening- and fining-up hemicycles, embedded within the major transgressive succession. These high-frequency cycles attest to the varied interplay of sedimentation, tectonics and sea-level changes, and the resultant net accommodations. A palaeogeographic model is proposed based on the high-frequency transgressive–regressive hemicycles, which envisages the evolution of the depositional environments in relation to the Cenomanian eustatic rise in the intra-cratonic riftogenic fluvio-marine transitional basinal setup.
