Late Permian palynoassemblage from Borehole No. WG-22 near Sekapur, Wardha District, Maharashtra, India

Abstract

The present paper deals with the palynological investigation of the Lower Gondwana sequence intersected in Borehole No. WG–22, drilled near Sekapur Village, in Wardha District, Maharashtra. The study divulges the incidence in significant proportion and with consistency of striate bisaccate palynomorphs, viz. Striatopodocarpites and Faunipollenites and non–striate genus Scheuringipollenites. The associated genera recorded include, Weylandites, Tiwariasporis, Densipollenites, Verticipollenites and Klausipollenites, though with meagre distribution. This palynoassemblage has been dated as Late Permian and affiliate closely with the palynofloral assemblages known from the basal part Raniganj Formation of East and West Bokaro coalfields, Damodar Basin, Makardhokada area of Nagpur District and vast areas of Godavari Valley. The study indicates that almost similar vegetational pattern existed in the Nagpur, Wardha–Godavari and Damodar basins however, there existed regional variations in the generic composition of the vegetation in Satpura Basin as suggested by their palynofloral contents. The mega– and microfloral studies of the Wardha Basin with particular reference to Sekapur area suggests prevalence of warm and temperate climate in this region.

Early Permian micro and megaspores from the Nand-Besur Block, Bandar Coalfield, Wardha Basin, Maharashtra, India

“…carried out by Bharadwaj and Anand Prakash (1974), Jha et al (2007) and Kalkar et al (2010) from the Makardhokada area in Umrer Coalfield, Nagpur District, by Bhattacharyya (1997), Mahesh et al, (2008Mahesh et al, ( , 2011Mahesh et al, ( , 2014 and Jha et al, (2011) (Sarate et al, 2016). Besides, Permian-Triassic (Srivastava & Bhattacharyya, 1996) and, early and late Triassic (Kumar & Jha, 2000) palynomorph assemblages have been recorded from Bazargaon and Katol area, respectively, of Nagpur District of the Wardha Basin.…”

Upper Pennsylvanian Age of the Lower Talchir Formation in the Wardha Basin, Central India, Based on Guide Palynomorphs Present in Radiometricallydated Palynozonations in South America, Africa, and Australia

“…A literature survey of the palynological works from Talchir sediments of the Wardha Basin is relatively less and requires further studies. Many palynologic studies were carried out in the lower Permian Barakar and upper Permian Kamthi formations (Agashe & Chitnis, 1970, 1972a, 1972bAnand-Prakash & Khare, 1974;Bharadwaj & Anand-Prakash, 1974;Agashe et al, 1981;Sarate, 1985;Bhattacharrya, 1997;Kumar & Jha, 2000;Jha et al, 2007;Sabina et al, 2007;Shivanna et al, 2008Shivanna et al, , 2011Shivanna et al, , 2014Kalkar et al, 2010;Kavali et al, 2010Kavali et al, , 2016Jha et al, 2011;Sarate et al, 2016Sarate et al, , 2017Murthy et al, 2017Murthy et al, , 2019.…”
