... of complementary thick ultramafic keels at the root of the island arc crust. Dunite, wehrlite, and Cr-rich pyroxenite from the Jijal complex, constituting the Moho transition zone of the Kohistan paleo–island arc (northern Pakistan), are often mentioned as an example of high-pressure cumulates formed...

... Abstract Mafic to ultramafic granulites in the northeastern part of the Jijal complex include two-pyroxene granulite, garnet-clinopyroxene granulite and garnet hornblendite. Field and textural relations indicate that two-pyroxene granulite is a relict left after formation of the garnet...

...M. Qasim Jan; Brian F. Windley; Robert N. Wilson Abstract Green chromian andradite occurs associated with chrysotile in a chromitite layer within the Jijal Complex (northern Pakistan). The garnet contains, on average, 10.1 wt. % Cr 2 O 3 (range 9.2-11.6%) and has a formula Ca (sub 3.04) (Cr (sub...

...HIROSHI YAMAMOTO Abstract In the Swat-Indus Kohistan area, lower crustal rocks of the Kohistan arc including amphibolites, granulites and ultramafic rocks are widely exposed. Detailed petrological-structural studies reveal that the Chilas-Jijal metamorphic complex comprises essentially intermediate...
