Palynological evidence for the Permian-Triassic Boundary in Sohagpur Coalfield, India

Abstract

Palynological analysis of the Upper Pali sediments exposed along the Chundi River Section has been discussed. The palynotaxa recovered from the above sediments reveal the presence of non-striate disaccate pollen in dominance along with the striate disaccate pollen. Besides, the other significant taxa recorded in the assemblage are Goubinispora, Playfordiaspora, Densoisporites, Lundbladispora, Nidipollenites, Satsangisaccites, Brachysaccus, Foveosporites, Staurosaccites, Todisporites, Converrucosisporites and Kamthisaccites. The overall palynoassemblages (I, II) decipher that the sediments of Chundi River Section have been deposited during Late Permian to Early-Middle Triassic period. Correlation of the palynofloral assemblages suggests that the sediments of the Chundi River Section lie between Nidpur bed and Tiki Formation of the South Rewa Basin.
