Basement rocks of the Lovingston massif in the central Blue Ridge anticlinorium include jotunite, anorthosite, charnockitic rocks, and related Fe-Ti oxide- and apatite-rich rocks that display strong similarities to lithologic assemblages elsewhere in the Grenville orogen. The rock units preserve evidence of a protracted history of granulite-facies metamorphism and plutonism from ca. 1.15 to ca. 1.0 Ga, followed by multiple episodes of lower-grade Paleozoic metamorphism. New whole-rock major-and trace-element data indicate systematic chemical trends, incompatible element enrichments relative to the lower crust, and overall uniformity among Lovingston rocks. Quantitative geochemical models and field associations support interpretation of the Grenvilleage Archer...
