Surghar Range is the outer most fold-and-thrust belt of the
sub- Himalayas making the easternmost extension of the Tran-Indus ranges (TIR)
bifurcated by the KaIabagh fault system from the western Salt Range of North
Pakistan.
The range follows east-west structural trend along the
sothern margin of the Kohat plateau and switches to north-south trend along the
easternmost flank of Bannu Basin. Along the range front the non-outcropping Permian to Eocene
rocks underneath the Kohat and Bannu Basin are exposed at surface.
The range displays arcuate structural style in plan and
exhibits distinct mountain forefront geometries along its map trace. It is
characterized by south facing structures along its east-west trending segment.
Whereas the north-south trending segment of the range is dominated east vergent
fold-thrust assemblages.
