The relationship between dry granitoid magmatism and UHT-metamorphism: Bakhuis granulite belt, western Suriname

The Bakhuis granulite belt (western Suriname) consists of an early Proterozoic high-grade supracrustal sequence characterised by ubiquitous compositional banding. Orthopyroxene is invariably present in both the mafic and dominant quartzofeldspathic lithologies. Locally, the Bakhuis belt has experienced ultrahigh-temperature metamorphic...

Charnockites and UHT metamorphism in the Bakhuis Granulite Belt, western Suriname: Evidence for two separate UHT events

The Bakhuis Granulite Belt in western Suriname is an ultrahigh-temperature (UHT) metamorphic terrain in the centre of the Paleoproterozoic (Transamazonian) Guiana Shield. Next to the UHT granulites, the belt contains a 30 by 30 km body of orthopyroxene-bearing granitoids: the Kabalebo charnockites. This setting offers an excellent opportunity to...
