The upper formation of the Miocene Dasht Murgha Group in the Pishin Belt of northern Balochistan, introduced by Kasi et al. (2012). It is a cyclic mudstone-dominated fluvial succession up to about 700 m thick — dark-red to maroon mudstone (intervals up to about 165 m) with subordinate coarse, pebbly, gritty sandstone — exposed in the core of the Dasht Murgha Syncline near Sra Khula village.

Contacts
Band colour = period; texture = dominant rock type. Lines between bands mark the contact type; dotted = no contact recorded in the sources (not a claim of conformity). 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.

Lithology (1)
-
The Sra Khula Formation is a cyclic alternation of sandstone and mudstone conformably above the Khuzhobai Formation, part of the Neogene Dasht Murgha Group fluvial succession of the Pishin Belt (Kasi et al. 2018).

Constituent units (1)
-
Kasi et al. (2012): uppermost formation of the Dasht Murgha Group; it transitionally and conformably overlies the Bahlol Nika Formation and is separated from the overlying Late Miocene–Pliocene Malthanai Formation (Zone IV) by a thrust.
