Question
AOA.
Sir what are the subdivisions of the potwar Basins(eg Northern, southern). and their stratigraphy as well. If possible attach a Stratigrphic column of these divisions.

Answer
Umer,

Potwar is generally taken to fall between Kalabagh fault in west and Jhelum fault in the east. The northern boundary is marked by Khairabad-Panjal Thrust, while Salt Range is the southern boundary. Within these boundaries it can be broadly subdivided into two parts, across the Khairi-Murat Thrust, as under:

i. North Potwar Deformed Zone (NPDZ)
ii. Southern Potwar

If you see the Tectonic Map of Pakistan (Kazmi and Rana, 1982), you will note that many E-W running faults are present north of the Khairi-Murat thrust, compared to its south.

The best thing for you is to get hold of 'Stratigraphy and Historical Geology of Pakistan' by Kazmi and Abbasi (2008), and  also different volumes of the ATC Proceedings. You will find strtigraphic column of not only Potwar but different other regions of Pakistan.
