Abstract

A garnet-hornblende-two pyroxene rock from Glenelg is described. It is assigned to the eclogite facies by virture of its density, mineral composition, and associations. Its chemical composition is that of a picrite-basalt. Comparison with other garnet-pyroxene assemblages suggests that there are no clear differences between the partition of major and minor elements in these minerals at the eclogite and granulite facies of metamorphism. A diagram to represent parageneses in basic and ultrabasic rocks of the eclogite facies is presented, and points of interest discussed.
