Phanerozoic granulites

Journal of the Geological Society, 1981
Granulites can form at every stage of the Wilson cycle: during plate accretion (Mid-Atlantic Ridge), in active plate margins of island-arc and Andean type (Ivrea Zone, main complex in Kohistan in the Karakorums), in the roots of Andean-type batholiths (Coast Range Complex, British Columbia; Santa Lucia Range of California), during the closure of a ...

Geochemical Comparison of Archaean Granulites in India with Proterozoic Granulites in Canada

1978
Abstract The charnockitic gneisses of North Arcot, Tamil Nadu, have a bimodal compositional distribution. The basic granulites show a tholeiitic Fe-rich trend, while the intermediate and acid charnockites show a calc-alkaline one, A similar compositional variation is apparent in amphibolite facies gneisses and asscciated mafic rocks and in the low ...

On the formation of granulites

Journal of Metamorphic Geology, 1991
The tectonic settings for the formation and evolution of regional granulite terranes and the lowermost continental crust can be deduced from pressure–temperature–time (P–T–time) paths and constrained by petrological and geophysical considerations. P–T conditions deduced for regional granulites require transient, average geothermal gradients of greater ...

Amphibolitization of Scourian granulites

Scottish Journal of Geology, 1974
Synopsis Scourian granulite-facies gneisses from north-west Scotland occur as relict masses surrounded by amphibolitized granulites. During amphibolitization the gneisses suffered both deformation and metamorphism. Ortho- and clinopyroxenes were replaced by hornblende and hornblende-quartz intergrowths forming corona textures.
