Precambrian crustal evolution and Cretaceous–Palaeogene faulting in West Greenland: Origin and evolution of the Kangâmiut mafic dyke swarm, West Greenland [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2006
The Kangâmiut dyke swarm in West Greenland intruded Archaean terrains at 2.04 Ga, and its northern portion was subsequently metamorphosed to granulite facies during the Nagssugtoqidian orogeny(c. 1.8 Ga).

Arc-related Alaskan type magmatism: evidence from pyroxenites associated with the Pakkanadu alkaline-ultramafic complex, Southern India

Frontiers in Earth Science
Petrological and major-trace element mineral chemistry studies have been carried out on pyroxenites from the Pakkanadu alkaline-ultramafic complex from the southern India to understand their origin and nature of magma responsible for ultramafic magmatism

Pressure-Temperature Conditions of Granulite Formation in Rogaland, SW Norway [PDF]

, 1994
The geology of SW Norway is dominated by high-grade amphibolite to granulite facies gneisses with associated migmatites and anorthosite-magerite complexes. Previous work suggests that metamorphism consisted of two high temperature events at 1.45 Ga (MI)
