“…Leiosphaerids indicative of marine influence are also known from Umaria coalfield (Srivastava & Prakash, 1984). Leiosphaerids recorded from the Dodhara area of Satpura Basin (Bharadwaj et al, 1978) allow an extension of the marine arm from Umaria and Manendragarh into the Central part of the Indian Peninsula.…”

Detailed palynological investigations have been carried out to reconstruct stratigraphy and interpretation of depositional environment of Tura and Pre-Tura sedimentary sections in Dhansiri Valley of Upper Assam Shelf, Assam & Assam-Arakan Basin. Sediments of the Tura Formation dated as Early Eocene and interpreted to be deposited under subtidal to inner shelf environment. Pre-Tura sediments, developed in studied wells, led to the identification of Dergaon, Bamangaon and Moabund formations with intervening unconformities, having different tectonic history and distinct palynofossil assemblages. Early Permian sediments of the Dergaon Formation (=Talchir Formation), the oldest in the basin are deposited under the intracratonic phase, overlie the metamorphic basement complex. The sediments of the Dergaon Formation are unconformably overlain by the Bamangaon Formation deposited during the Early Cretaceous, whereas, in well DR-A, the sediments of the Dergaon Formation are directly overlain by the Moabund Formation corresponding to the Late Maastrichtian age. The sediments of the Tura Formation overlie the Maobund Formation in well DR-A, and they overlie the Bamangaon Formation in the rest of the wells in Dhansiri Valley.

“…The determination of epoch and age of these assemblage zones has been discussed by Bharadwaj et al (1979), Tiwari and Vijaya (1992), Ghosh et al (1996), Tiwari (1999a, b, c), and others, based upon palynology, plant megafossils, estheriids, nonmarine vertebrate fossils, palynological cross-correlation with the well-dated Tethyan succession of the Himalaya, sequence stratigraphy and inter-regional relationship with comparable levels in Australia, Madagascar and Antarctica.…”

The concept of Gondwana Sequence on the Indian Peninsula is discussed from the viewpoint of time, geographical extent and environment. It has been ascertained that Talchir deposition began in the late Asselian (Early Permian) and not during the Permo-Carboniferous. The Karharbari succession is a distinct formation. The Barakar Formation should continue to be placed in the Lower Permian of the bipartite division of the Permian System. The Banspitali Nala section, in the south of Damodar River, Raniganj Coalfield. West Bengal, India, maybe a suitable nonmarine reference section for the Permian-Triassic boundary. To determine the age-ranges of the palynozones through the Gondwana Sequence, there is a need for cross-correlation with sections in the Himalayan region and in other areas of Gondwanaland.

A Talchir mioflora from Northern Satpura Basin, India

Abstract: A mioflora from Northern Satpura Basin has been found to contain radial monosaccate miospore genera, alongwith abundant alete miospores. Its similarity with the mioflora of Umaria marine beds is suggestive of Late Talchir age and the marine palaeo-environment.
