Unakite is a coarse-grained metamorphic rock that is an altered granitoid composed of orthoclase feldspar (pink), epidote (yellow-green), and quartz (smokey or colorless). Albite-oligoclase plagioclase (white) may or may not be also present.
Bradley first defined and described Unakite in 1874. He named it for Unaka Range of the Great Smoky Mountains of western North Carolina and Eastern Tennessee. He collected his samples primarily from "The Bluff", "Walnut Mountain", and "Max's Patch" in Cocke County, Tennessee. thumb|Bear carved from unakite. Length 8 cm.
