A section of the middle Eocene Kohat Formation has been measured from the Gumbat area, Kohat Basin, northern Pakistan for detailed biostratigraphic and micropalaeontological study. A total of 44 samples were collected from bottom to top, according to the variation in facies. Of these samples, 50 thin-sections were prepared. Fifteen age-diagnostic species of larger foraminifera were recorded. Based on these age-diagnostic species, a late Cuisian to middle Lutetian age is assigned to the Kohat Formation. This age falls within SBZ 12 to SBZ 14 according to the Standard Shallow Benthic Biozonation (SB Zonation). Four microfacies and eight subfacies have also been recorded ranging from grainstone to mudstone. On the basis of foraminiferal assemblages and the microfacies analysis, it can be concluded that the Kohat Formation in this area might have been deposited in a shallow-shelf, low- to moderate-energy environment with free circulation of water.
