Structural analysis of the Kharthop and Kalabagh Hills area,Mianwali District,Punjab,Pakistan

The surghar range and the kalabagh hills are the extension of the western salt range and are comprised of precambrian to mesozoic platform and plio-pleistocene fluvial sediments. the eastern surghar range is a thin-skinned deformed structural province characterized by contractile structures. the dominant structural geometry of the range includes south-verging frontal thrust and folds and steeply south dipping back thrusts. this geometry developed as a result of ramping from a basal decollement at the base of precambrian to cambrian rocks. the contractile deformation systematically changes to transpersonal deformation in the east along the kalabagh fault zone and a combination of s alt tectonics and compressional deformation in the vicinity of the kalabagh hills. the structures related to salt intrusions include the development of normal fault in the vicinity of kalabagh hills that are believed to be gravitational collapse caused by the flowage and upsection migration of precambrian salt range formation. © 2016,national centre of excellence in geology. all rights reserved.
