A low-grade metasedimentary group (the Girarai and Tursak formations) of the Lesser Himalaya south of the MCT.

Bampokha group is named by Chaudhry et al. (1992) for the Girarai and Tursak formations exposed in the south of MCT in the Lesser Himalaya and consists of low-grade clac schist and marble and graphitic schist. According to Chaudhry et al. (1992) this group is different from Alpurai schist group in its tectonostratigraphic position and age.

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.
