Preservation of granulite in a partially eclogitized terrane: Metastable phenomena or local pressure variations? [PDF]
, 2021 Granulite is preserved over large areas of partially eclogitized and hydrated rocks on Holsnøy, Bergen Arcs, Norway. The interfaces between granulite and eclogite are sharp on a hand-specimen scale and contain microstructural and compositional evidence ...

Evolution of migmatitic granulite complexes: Implications from Lapland Granulite Belt, Part I: Metamorphic geology [PDF]
Bulletin of the Geological Society of Finland, 2006 The Palaeoproterozoic Lapland granulite belt was juxtaposed between Archaean and Proterozoic terrains in the NE part of the Fennoscandian Shield concurrently with the accretion of Svecofennian arc complexes at ~1.9 Ga.

Fluid-induced metamorphism and anatexis of refractory Ni-Co-Cu sulphides in subduction-related rocks [PDF]
E3S Web of Conferences, 2019 The role of metamorphism on refractory sulfides is not well constrained. Although experiments have displayed the effectiveness of high grade metamorphism, namely granulite facies metamorphism, on sulfide anatexis, its role in the presence of other ...
