North View granite (Bentley, 1992). Light-gray, fine to coarse-grained, lineated to foliated to massive alkali granite composed of blocky alkali feldspar mesoperthite, quartz, magnetite, and minor aegirine, riebeckite, biotite, allanite, titanite, fluorite, zircon, and garnet. Minor microcline and albite form separate phases with recrystallization. Garnet, which may be metamorphic in origin, is grossular-almandine-spessartine with up to three percent yttrium; riebeckite is in the plane of foliation and is metamorphic in origin. The northern and western borders of the pluton are fine-grained and granophyric, with phenocrysts of mesoperthite, albite, and quartz; accessory and secondary minerals include magnetite, biotite, garnet, titanite, chlorite, epidote, muscovite, and calcite.
