Zusammenfassung:[...]we interpret that the origin of the shear zones in the studied area is dynamically related with the neo tectonic of the Makarwal Anticline, while tensional joints are episodically related with the formation and uplifting of the Makarwal Anticline. All these ranges of Trans Indus Rages encircling and dipping towards saucer shaped Bannu Basin showing sharp change in their strike. [...]these contain a number of large faults along the margin of the basin. In Shanawa area, where the strike of the strata is about NS, these joints display north south compression and east-west extension showing effect of compression from east. [...]we interpret that the origin of shear zones in Shanawa area is related with the neo-tectonics of the area, while tensional joints and shear zones further suggest that the southern tip of Makarwal Anticline structurally developed under trans-tensional regime. [...]we interpret that the origin of the shear zones in the studied areas is dynamically related with the neotectonics of the Makarwal Anticline, while tensional joints may episodically have related with the formation and uplifting of Makarwal Anticline.
