A Precambrian limestone of the Hazara hills near Miranjani.

The Miranjani Limestone is a named limestone unit within the Hazara Group (Latif, 1970) of the Hazara region. The enclosing Hazara succession (Hazara Formation of Calkins et al., 1969) is a Late Precambrian sequence of slate, phyllite, shale and limestone with graphitic layers, correlated with the Dogra Slates.

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.
