The central Kohistan-arc group — Gilgit, Gashu-Confluence Volcanics and Thelichi — recording Jurassic–Cretaceous island-arc volcanism and sedimentation.

Jaglot group ( Middle Jurassic-Middle Cretaceous ) is named by Khan T. et al. (1994) for the Gilgit formation, Gashu-confluence volcanics and Thelichi formation.

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.
