Metamorphism of Granitoids

1994
Granitoid rocks comprise granites, alkali-feldspar granites, granodiorites and tonalites, and constitute a large portion of the continental crust. Because the main constituents — alkali-feldspar, plagioclase, quartz, biotite, muscovite, hornblende — are found over a wide range of P-T conditions, this rock group is not a very useful indicator of ...

Proterozoic Granitoids of Rajasthan

Journal of the Geological Society of India, 2005
Abstract Two granitoid bodies each from Palaeo-, Meso- and Neo-proterozoic periods have been studied for their chemical, petrological and source characteristics The Proterozoic granitoids are megacrystic as well non-megacrystic with variable effect by tectonometamorphic events The Palaeo-proterozoic granitoids are peraluminous ...

Metamorphism of Granitoid Rocks

2002
Granitoid rocks comprise granite, alkali-feldspar granite, granodiorite and tonalite. They constitute the largest portion of the continental crust. Granitoid gneisses, commonly migmatites, are in fact the dominant rock type of the continents. Because the main constituents — alkali-feldspar, plagioclase, quartz, biotite, muscovite, hornblende — are ...

Tectonic discrimination of granitoids

Geological Society of America Bulletin, 1989
Granitoids as categorized by tectonic environment are (1) island arc granitoids (IAG), (2) continental arc granitoids (CAG), (3) continental collision granitoids (CCG), (4) postorogenic granitoids (POG), (5) rift-related granitoids (RRG), (6) continental epeirogenic uplift granitoids (CEUG), and (7) oceanic plagiogranites (OP).

Ultrametamorphism and granitoid genesis

Tectonophysics, 1977
Abstract A model is presented to explain the geochemical and mineralogical characteristics of granitoids and their inclusions. The product of ultrametamorphism is melt + residuum, both of which may move en masse to the site of crystallization. The nature of the source material can be deduced from studies on the granitoids and their inclusions; based
