2.3.7 GANGA-PUNJAB BASIN

Ganga-Punjab is a Category III basin with entirely undiscovered in-place, that calls for intense
exploration for a potential discovery.

The basin overlaps with the state(s) of Bihar, Chandigarh, Delhi, Haryana, Himachal Pradesh, Jammu
and Kashmir, Madhya Pradesh, Punjab, Uttar Pradesh, Uttarakhand.

Ganga-Punjab basin is covered by thick alluvium,
which conceals the pre-collisional (Indo-Eurasian
plates) Proterozoic and post-collisional Tertiary
records. Post-collision flexuring of the Indian
lithosphere and thrust-fold loading produce the
Himalayan peripheral foreland in Early Miocene.
The basin expanded during Middle Miocene
and attained its present configuration in Late
Quaternary.
