Comments	Blue Ridge Anticlinorium, Central. From expanded explanation (ref. VA002): Micaceous quartzite. Coarse-grained micaceous quartzite and feldspathic metasandstone with interbedded metasiltstone and phyllite; occurs above Catoctin greenstone (CZc) in an outlier surrounded by Mesozoic rocks east of Culpeper. These rocks are lithologically similar to, and probably correlative with micaceous quartzites in the True Blue formation of Pavlides (1989, 1990), and with feldspathic metasandstone lenses in the Candler Formation.
