Palynofloras recovered from core samples from two bore-holes MK 327 and MK 332 drilled near Kapurdi, Barmer, Rajasthan are rich and diversified. Restricted occurrence of Matanomadhiasulcites maximus and Triangulorites pachyexinus alongwith other long-ranging taxa demarcates the Palaeocene sediments from those of Eocene. Presence of Eocene sediments in the studied bore-holes is indicated by the restricted occurrence of Meliapollis pachydermis, M. symplex, Lygodiumsporites lakiensis and Foveotricolporites reticuloidus. Two palynological zones, Assemblage Zone A indicating Late Palaeocene age and Assemblage Zone B indicating Early Eocene age, have been identified in the bore-hole sequences and sediments representing these zones have been correlated with Akli and Mataji Ka Dungar formations, respectively of the Barmer Basin.
