โœฆ Synopsis

Green and Vernon (1974)

have experimentally determined a divariant field of cordierite-orthoamphibole-kyanite-quartz with a slope of 12___4 bars per ~ occurring between 8.0 and 10.4 kbar at 750 ~ C and between 9.5 and 11.3 kbar at 850 ~ C. However, the writers' thermodynamic calculation of the divariant band indicates a more limited range of 0.65 and 0.7 kbar at 750 ~ C and 850 ~ C respectively, with an estimated error of + 0.2 kbar.

Clear evidence exists for a cordierite breakdown reaction to amphibole-kyanitequartz in high-grade metamorphic rocks of the Arunta Complex, Australia. Using the natural minerals this reaction has been duplicated experimentally. It proceeds over a divariant band with a slope of 12 4-4 bars/~ occurrin

A series of experimental runs has been conducted on a glass prepared from a natural island arc calc-alkaline andesite from Fiji. The crystallization sequence was determined for the pressure interval 9-36 kb under anhydrous conditions and with 2, 5, and 10% by weight of water carefully added. Additi
