Palynozonation of Middle Pali Member in Sohagpur coalfield, Madhya Pradesh

Abstract

Three palynological assemblages have been identified in a Bore-hole SPB-18 (26.0-163.80 m depth) in the Middle Member of the Pali Formation. The older two assemblages contain the abundance of striate-disaccate pollen, i.e., Faunipollenites and Striatopodocarpites which are followed by Crescentipollenites. Besides, Gondisporites, Corisaccites, Lunatisporites and Chordasporites are other important genera which indicate a Late Permian age of the horizon. Presence of Leiospherids at the top of the sequence (Assemblage-I) suggests a probable marine influence in the area. In the Assemblage-II, a new disaccate pollen- Protoeusaccites has been recorded which exhibits a transitionary phase from protoeusaccate to eusaccate in the development of saccus.
