Kohat-Potwar Basin (Upper Indus)

Kohat Basin

Khyber Pakhtunkhwa, south of Peshawar · Foreland fold-and-thrust belt

Western part of Upper Indus Basin, salt-tectonics dominated. Trans-Indus region with excellent Paleocene-Eocene exposures. Known for gypsum deposits, Bahadurkhel Salt, and petroleum potential. Shows transition from marine to continental conditions with unique Panoba and Kahan facies.

Band colour = period; texture = dominant rock type. Lines between bands mark the contact type (wavy = unconformity inferred from a missing period). True scale makes height ∝ recorded thickness; hatched = thickness not recorded. Ages approximate, for ordering.
