The petrology of an ultrametamorphic complex is described. High-grade migmatitic plagioclase gneisses and amphibolites, with quartzites and metamorphic pyroxenites, were intruded sub-concordantly by gabbro. These older rocks were intruded by magmatic plutons of pyroxene-microperthite quartz-monzonite, with hornblende-microperthite quartz-monzonite and migmatitic microcline granite. Late basic sills and granite dykes occur.
