Abstract:
This research is carried out in central to western Salt Range near vicinity of
Nurpur village and Kallar Kahar. Surface and subsurface geological data is
incorporated to construct two North South geological cross sections. The interpretation
suggest that Salt Range Thrust emanates from basal detachment at crystalline
evaporites, cuts up section as fault bend folds and terminate as blind thrust on Punjab
plain. The strata above the Salt Range Thrust is evolved as multi bend fault bend fold
with a series of anticlines and synclines, which are partially eroded and provide
sediments to Punjab plain in the South. Tapering of layers is also interpolated to be
present in foot wall in order to be in accordance with well data. However, in hanging
wall a thrust fault is observed exactly above the foot wall ramp of the thrust system. In
the basement rocks, a ramp resulting from pre-existing Normal fault is present which is
also interpreted in previous work. The subsurface setting and the surface folds and
faults are evolved in response to collapse of competent younger strata over weaker
evaporites deposits of Salt Range Formation which manifest the idea of salt tectonics
in the region.
