UHT metamorphism on Seram, eastern Indonesia: reaction microstructures and P-T evolution of spinel-bearing garnet-sillimanite granulites from the Kobipoto Complex.
The island of Seram, part of the northern limb of the Banda Arc in eastern Indonesia, exposes an extensive Mio-Pliocene granulite facies migmatite complex (the Kobipoto Complex) comprising voluminous leucosome-rich diatexites and scarcer Al–Fe-rich residual granulites. The migmatites are intimately associated with ultramafic rocks of predominantly lherzolitic composition that were exhumed by substantial lithospheric extension beneath low-angle detachment faults; heat supplied by the lherzolites...[Show more]
