330   $aGrenvillian terranes of eastern Canada are characterized by large titanium deposits and the association anorthosite-ferrodiorite-charnockite-granulite. The Roseland district of Nelson and Amherst Counties in central Virginia (figure 1) is the only terrane of the southern Appalachians known to have this association; titanium deposits include rutile in the anorthosite border zone and ilmenite in nelsonite and ferrodiorite. The anorthosite is unusually alkalic with a combined Na20 + K20 content of 8.4% (Table 2), about 1½ times the world average for massif anorthosites (Nockolds, 1954).
