The Eocene beds of the Kohat district

Abstract

The Kohat district forms part of the North -West Frontier Province. It is bounded by the river Indus on the east, by part of the Peshawar district in the north-east, by the Tirah along most of its northern border, by the luri country on the north -west, by Waziristan on the west, and by the Bunnu and Mianwali districts on the south-west and south-east respectively. Its shape is indicated by "Text- figure 1, and its area is approximately 2,500 square miles.The Kohat district is the most rugged portion of the North-West Frontier province. It is essentially mountainous, except to the south-east, where it is penetrated by a tongue-like extension of the plains of the Bunnu district to the south. Its south-eastern border is nevertheless mountainous, being formed by the crest of the Punjab Salt Range, which rises some 4,000 set above the level of the adjoining plains, and swings to west and south after crossing the Indus at Kalabagh.
