Abstract

The Karakoram batholith along the Baltoro glacier transect separates a northern sedimentary domain with structural culmination of high-grade gneisses (K2 gneiss) from a southern high-grade metamorphic domain. The Baltoro plutonic units range in composition from biotite granodiorite to garnet bearing two mica leucogranite; they have no mafic dykes and no volcanic component. The Baltoro granite is interpreted as being crustally derived from partial melting of deeper level rocks equivalent to the high-grade metamorphism, crustal-scale ductile shearing, migmatisation and magmatism are discussed.
