The Baroghil-area counterpart of the Chapursan Group — a thick, fossil-rich Permian shale-and-limestone succession.
Lashkargaz formation is named after the Lashkargaz village in the upper Yarkhun valley 10km ESE of Baroghil Pass by Gaetani et al. (1995) and he presented members of siltites, packstone, wackstone, shales and marls of Early Permian age. 16

Contacts
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.
