Location of the collection area “Chabbar Syedan” site in Jhelum district with outcrops exposed in the vicinity of the village.
Lithological column of the surveyed area in the Chabbar Syedan, Potwar Plateau, Pakistan. The area represents the Chinji Formation of the Lower Siwaliks and other formations are missing from the surveyed area.
