Abstract

The calc-alkaline Munster Suite comprises folded sheet-like bodies of mafic to intermediate orthogneiss which intruded the Leisure Bay Formation and Glenmore Granite. It varies compositionally from medium-grained, quartz-free, two-pyroxene mafic granulite to coarse-grained, porphyritic, two-pyroxene (charnockitic) quartz-monzonite. Coherent trends on Harker variation diagrams and constant Nb/Y ratios suggest a cogenetic origin for the different exposures of the Munster Suite. Mineral textures indicate prograde metamorphism from amphibolite to granulite facies. The absence of garnet from the two-pyroxene mafic granulites indicates metamorphic pressures below 11 kb. Low P_H2O and high P_CO2 during the emplacement and metamorphism of the Munster Suite is suggested. -from Authors
