The present study is focused on evaluation of deep marine pelagic sediments of Late Cre-taceous Kawagarh Formation of Kala-Chitta Range in the context of microfacies analysis,paleoenvi-ronmental interpretation,planktonic foraminiferal biostratigraphy,sequence stratigraphy and diversi-fication of species.A total of thirty three rock samples were collected from the measured section.Three microfacies are interpreted,namely planktonic foraminifera wackestone,planktonic foraminifera mud-stone and sandy mudstone indicating low energy depositional environment i.e.,outer ramp.The bio-stratigraphic studies show plentiful planktonic foraminifera species of Globotruncana,Heterohelix and Globotruncanita.However,no association of benthic or siliceous organisms was observed.On the basis of available species assemblage,a single local planktonic foraminifera biozone i.e.,Globotruncana-Heterohelix-Globotruncanita Assemblage Biozone is established.The biozone information is combined with published literature and Lower Santonian to Middle Maastrichtian age has been assigned to the Kawagarh Formation.The trend of species occurrences evinces that species number decreases over time with pulsated rise in the Kawagarh Formation.The Kawagarh Formation carbonates show an overall Transgressive Systems Tract(TST).The Kawagarh Formation of Pakistan evinces analogous characteristics to that of the Late Cretaceous Gurpi Formation of Iran based on the geologic age,out-crop lithology,microfacies,planktonic foraminiferal assemblages,depositional setting and sequence stratigraphy.
