Abstract

The distribution of isograds indicates a northwest to southeast increase in the intensity of metamorphism in the Uwet area from medium greenschist facies to uppermost amphibolite facies. The presence of kyanite and sillimanite indicate high pressure-high temperature Barrovian-type regional metamorphism whereas the absence of staurolite in these alumina-rich rocks is indicative of the high fugacity of oxygen during the metamorphism of the area.
