Comments Includes orthogneiss, granite, and marble with minor pyroxenite, greenstone, meta-quartz diorite, and hornblendite in the northern Cascade Mountains (Yellow Aster Complex) (Dragovich and others, 2002). Amphibolite with minor schist, metadiorite, metagabbro, and tonalite gneiss in Kittatas County (Walsh and others, 1987). Metaplutonic rocks are listed as their protoliths below but specified as partially metamorphosed in the lithology coding comments.
