Stratigraphy of the Bannu and Dera Ismail Khan areas, Pakistan

Abstract

The Bannu and Dera Ismail Khan quadrangles cover an area of more than 8,600 square miles in north-central Pakistan, between lat 31 and 33N. and long 70 and 71E. This area contains two main physiographic units: the alluvial lowlands, which include the structurally undisturbed Indus and Bannu plains, and the folded belt, which includes the Khisor, Marwat, Bhittanni, and Sulaiman Ranges, as well as the highlands of Waziristan. These ranges and highlands form a nearly continuous mountain system between the Salt Range-Potwar Plateau region to the northeast and Baluchistan to the southwest.
