Summary:

Named as member of Flat Ridge Formation. Named for Cinnamon Ridge, 1 mi west of Gossan Lead District, Grayson Co., southwestern VA. Consists of blue dense basalt, with veins of epidote and red jasper, a green amygdaloidal basalt with epidote-filled vesicles, and a tuff. These are underlain by an agglomerate and flow breccia containing angular blocks of purplish-blue flow-banded vesicular basalt, of red rhyolite, of red jasper, and of granite, in an epidotic groundmass. Thickness is about 90 ft. Beds thin out east of Wolfpen Branch. Lies near base of Flat Ridge Formation. Age is Precambrian.
