Jha N., Saleem M. & Aggarwal N. 2013. Palynological investigation of subsurface Lower Gondwana sediments in Gundala area, Lingala-Koyagudem Coalbelt, Godavari Graben, Andhra Pradesh, India. Geophytology 42(2): 85-92. Qualitative and Quantitative analyses of the palynoflora obtained from borecores, SGK-2, SGK-3 and SGK-4, drilled near Gundala, Godavari Graben, Andhra Pradesh, have been carried out. The palynoassemblage, containing 23 genera and 38 species, is characterized by dominance of radial monosaccates (chiefly Parasaccites) and subdominance of non-striate disaccates (chiefly Scheuringipollenites). This association, along with presence of Crucisaccites and few striate disaccates, suggests its resemblance with palynofloras obtained from the Upper Karharbari Formation of other basins (Late Sakmarian - Early Artinskian). Presence of Upper Karharbari palynoflora has been demarcated in lithologically designated Lower Barakar Formation.
