  • Unakite - (metamorphic rock)
    "Unakite is a metamorphic rock composed primarily of pink. red, and orange feldspar, gray quartz and dark green epidote. Other minerals which may occur in minor amounts include apatite, biotite, magnetite, pumpellyite and zircon. 

More info.

    "The name unakite was applied by Bradley" in 1874 to a variety of granite from the Unaka Mountains in North Carolina, composed of the essential minerals yellow-green epidote, pink feldspar, and quartz. Unakite has since been noted at two localities in Virginia— (1) at Milams Gap, near Luray, in Page and Madison counties,6 in the Blue Ridge of northern Virginia, and (2) about 2J miles south of Troutdale, Grayson County," in the Blue Ridge region of southwestern Virginia.

The mineral composition of the unakite from the Virginia and North Carolina-Tennessee localities places it among the granites, with epidote as an essential constituent, but, according to an analysis by Phalen, quoted below, of specimens from Milams Gap, Virginia, the rock is relatively basic for a granite.

In the Milams Gap locality the unakite is a moderately coarse but irregular crystallization of red feldspar, quartz, and green epidote. Irregular crystallization of the rock is shown in the variation from masses composed of more than two-thirds of the red feldspar through all gradations to masses composed of quartz and epidote without feldspar—epidosite.d Thin sections of the unakite from Milams Gap show epidote, orthoclase, quartz, iron oxide, zircon, and apatite. The epidote is here secondary, as in the other localities, replacing pyroxene and feldspar, both plagioclase and orthoclase. The unakite from Grayson County, Va., shows deeper-colored feldspar and epidote than that from Milams Gap. Analyses of the unakite and the unakite-bearing rock at Milams Gap are given on page 78."
