The Jijal complex, covering more than 150 sq. km in the extreme north of Pakistan, is a tectonic wedge of garnet granulites intruded in the south by a 10 × 4 km slab of ultramafic rocks. The granulites are divisible into plagioclase-bearing (basic to intermediate) and plagioclase-free (ultrabasic to basic) types, the two types reflecting differences in bulk chemistry. Garnet + plagioclase + clinopyroxene + quartz + rutile ± hornblende ± epidote is the most common assemblage. The plagioclase-free rocks are composed mainly of two or three of the minerals garnet, amphibole, clinopyroxene and epidote. Orthopyroxene occurs in websteritic rocks devoid of epidote. Much of the amphibole and some epidote appear to be prograde products. Although variation diagrams do not reveal a genetic link between the two types of granulite, it is considered that they are comagmatic rather than the products of two or more unrelated magmas.
