The Talchir Formation of Permian age is the lowermost lithostratigraphic unit of the Indian Gondwana successions preserving a record of the Late Paleozoic glaciation that affected the whole Gondwanaland. The formation unconformably overlies the Precambrian basement in all the Gondwana basins of India, and marks initiation of sedimentation after a long hiatus since the Proterozoic. The Talchir Formation of the Satpura Gondwana basin of central India shows features diagnostic of deposition under glacial regime such as the presence of diamictites, boulder pavements, bedding plane striation, faceted/striated gravels, bullet-shaped clasts, dropstone, cryoturbation, etc. The Talchir strata of the Satpura basin, in addition to tidal signatures, contain marine bivalve and trace fossils. A proglacial marine environment is thus inferred for their deposition. The dominant lithologies are conglomerate, pebbly sandstone, sandstone and shale with little limestone, which can be classified into the following major facies:• matrix-supported conglomerate, • clast-supported conglomerate, • cross-stratified, channel form pebbly sandstone, • hummocky, swaley or low-angle cross-stratified pebbly and non-pebbly sandstone, • turbidite/tempestite sheet sandstone, • massive to fissile, green to black claystone with carbonate layers and nodules.The conglomerates are interpreted as deposits of a spectrum of sub-aqueous sediment gravity flows including debris flow, hyperconcentrated/concentrated density flow and grain flow. The crossstratified pebbly sandstone bodies, on the other hand, represent braidplain delta deposits of glacial outwash origin. Hummocky, swaley, low-angle cross-stratified sediment bodies were deposited by storm-generated combined flows in a shoreface setting. In contrast, the sheet sandstone bodies are products of turbidity currents and storm-induced density currents in an inner shelf setting below fair weather wave base. The claystone facies is interpreted as a product of suspension fallout from hypopycnal sediment plumes in the outer shelf domain below storm wave base. All the lithofacies described above occur repetitively in the succession. Three facies-associations have been recognized in the Talchir Formation, representing ice-contact fandelta, outwash braidplain delta and a virtually ice-free, non-deltaic open marine realm. The different marine facies of the Talchir Formation define a number of shallowing-upward packages, which are arranged in the succession with a retrogradational trend to result in an overall fining-and deepening-upward succession. The overlying coal-bearing Barakar Formation has been interpreted to have formed in a tide-wave influenced deltaic setting with a marine, prodeltaic part. The strata that are transitional between Talchir and Barakar Formations show preservation of abundant plant materials suggesting gradual warming. The three facies-associations of the Talchir Formation also point towards progressive decrease in the intensity of glacial activity, inducing changes in the paleogeography ...

“…The nature of sediment and associated sedimentary structures clearly indicate marine influence in the upper part of the succession (Chakraborty, 1993;Bhattacharya, 1996, Ghosh et al 2004). Marine fossils dominated by Eurydesma and other Pelecypods, Brachiopods, Bryozoans, foraminifera has been recorded from the top of Talchir and equivalent formation from many basins like Umaria, Manendragarh, Daltonganj, Satpura and Rajasthan within peninsular India and all along the Tethyan margin (Reed, 1939;Ghosh, 1954;Mishra et al 1961;Dutt, 1965;Dutt and Shah, 1969;Dickins and Shah, 1977;Ranga Rao et al 1977;Ghosh, 2003). Sporadic occurrence of various types of marine fossils are also reported from Raniganj, Bokaro, Rajmahal, Jharia, Ramgarh, Godavari, Athgarh, Palar Basins (Venkatachala and Rawat, 1973;Tewari et al 1981;Rawat and Jain, 1985;Ghosh et al 1987;Tewari, et al, 1987;Banerjee and D'Rozario, 1988;Chaudhuri and Mondal, 1989;Pal et al 1994).…”

“…Marine incursion from northern Tethyan margin has also been envisaged (Veevers and Tiwari, 1995;Ravi Shanker et al 1996). Ghosh (2003) proposed a single marine front from east. However, considering the wide occurrence of marine imprints in almost all the basins, particularly the marine occurrences in Palar Basin as well as in Damodar Valley Basins and southern part of Mahanadi Valley, it is difficult to explain all the marine occurrences by incursion either from east or north only.…”

Stratigraphic correlation between different Gondwana Basins of India

et al. 2010

Gondwana Basins of India occur within the suture zones of Precambrian cratonic blocks of Peninsular India along some linear belts. More than 99% of the total coal resource of the country is present within these basins. The basins are demarcated by boundary faults having graben or half-graben geometry.These basins preserve a thick sedimentary pile deposited over nearly 200 million years from latest Carboniferous to Lower Cretaceous. However, due to lack of well-constrained data, age of most of the formations is assigned tentatively. This has resulted in diversified views on both intra-and inter-basinal stratigraphic correlation particularly in case of Upper Gondwana formations.It is well recognised that there are distinct spatial and temporal similarities in lithological, faunal and floral distribution in different Gondwana Basins of southern continents, including India, that were once part of supercontinent Gondwanaland.To address the problems of Indian Gondwana stratigraphy, during the present study, some unique events, also recognised in other parts of Gondwanaland, like marine flooding surfaces, large scale tectonic events or major change in depositional environment have been used as a tool for temporal correlation within the Gondwana Basins of India. Many of these events have been dated from different basins elsewhere. Considering these major events as time planes the total time span of deposition in Gondwana Basins has been classified into seven time slots. Recognition of these time planes helps in interbasinal correlation of different formations in Indian Gondwana basins and assigning the age, wherever available. This approach also helps in better understanding of basinal history. Unless otherwise mentioned, the time scale proposed by International Commission on Stratigraphy (2004) has been followed in this paper.

“…The available paleogeographic reconstructions suggests that the Satpura Gondwana basin had migrated from a position of 60°S latitude in Early Permian to 30-40°S latitude by Middle Triassic (Scotese, 2001(Scotese, , 2002Ghosh, 2003;Ghosh et al, 2006) and thus had traversed through different climatic zones during this period. During this movement, the climate changed from cold (glacial), arid (Talchir Formation) to temperate, humid (Barakar Formation), to warm, subhumid/semiarid (Denwa Formation; Ray and Chakraborty, 2002;Ghosh et al, 2004;Chakraborty and Sarkar, 2005;Ghosh et al, 2006;Chakraborty and Ghosh, 2008).…”
