Summary:

Grenvillian [Middle Proterozoic] rocks cropping out in eastern Piedmont of VA in region called Goochland terrane by Horton and others (1989) or Goochland granulite terrane by Farrar (1984). Lithic sequence (ascending) consists of State Farm Gneiss (felsic to intermediate gneisses of both igneous and sedimentary protoliths), Sabot Amphibolite (mafic volcanic protolith), and Maidens Gneiss (heterogeneous unit that is probably metavolcanic and metasedimentary in origin). Maidens is continuous to the north with Po River Metamorphic Suite, correlative to the south with Raleigh Gneiss of Farrar (1985) in NC.
