Band colour = period; texture = dominant rock type. Lines between bands mark the contact type. True scale makes height ∝ recorded thickness; hatched = thickness not recorded. Ages approximate, for ordering.

This unit (highlighted) within its province column; faded ends continue above and below. Line style marks the contact type.

A Pleistocene gravel-rich molasse, one of the youngest units of the foreland.

Dada Formation Its name is derived from Dada River south of Spintangi Railway station (HSC, 1961). It consists of conglomerate with subordinate shale and sandstone. At places it also includes the white and red muds especially in the valley areas. Its lower contact with Chaudhwan Formation and upper contact with Sakhi Sarwar Formation is angular and at some places transitional. According to stratigraphic position, its age may be Pleistocene.
