Amphibolite-granulite facies charnockites

Proceedings of the Indian Academy of Sciences - Section A, 1953
The Cheri Hill in the Madras type area of charnockites, shows on careful mapping the folding of bands of leptynite and basic charnockites. The mineralogy of the basic types gives striking evidences of the metamorphic origin of charnockites. The rocks have been subjected to some little retrograde metamorphism and are ascribed to the almandine-diopside ...

CLASSIFICATION OF AMPHIBOLITES

Geological Society of America Bulletin, 1963
Research on amphibolite problems has mainly been concentrated on the chemical differences between ortho- and para-amphibolites with little attempt at a classification of rock types. Therefore, a simple classification of amphibolites ( sensu lato ) is presented to include amphibolites ( sensu stricto ), plagioclase amphibolites, and quartz amphibolites.

Amphibolite facies conditions in the oceanic crust: example of amphibolitized flaser-gabbro and amphibolites from the Chenaillet ophiolite massif (Hautes Alpes, France)

Earth and Planetary Science Letters, 1978
Abstract Petrological and mineralogical data on amphibolitized gabbros from an Alpine ophiolite massif (Chenaillet Massif, France) are presented. Comparison with metagabbros dredged from the ocean floor shows that synkinematic amphibolite facies conditions may be reached in gabbros after their initial crystallization in the vicinity of the ridge.

Amphibolitization of metagabbros in the Scottish Highlands

Journal of Metamorphic Geology, 1986
Abstract Compositions of actinolite, hornblende and cummingtonite, together with pyroxene and plagioclase, are studied in basic intrusions in the Dalradian of north‐east Scotland, and the Glen Scaddle complex in the West Moine. Amphibolitization is due to influx of water from the country rocks.

Generation of granites after amphibolites

Petrology, 2006
This paper presents the results of a comprehensive experimental study of the formation of granitoid melts at the expense of olivine-normative amphibolites. It was shown that trondhjemite-tonalite and granite-granodiorite melts can be generated by incongruent melting reactions at pressures of 5–25 kbar at T = 800–1000°C.
