Summary:

The Roses Mill Plutonic Suite, here named, includes the Roses Mill and Turkey Mountain plutons in the Roseland district, Nelson and Amherst Cos., VA. Four dominant rock facies are present: primary charnockitic ferrodiorite, secondary biotite augen gneiss, dike rocks in older formations, and nelsonite. The plutons intrude the anorthosite-granulite terrane, including the Roseland Anorthosite and charnockitic rocks of the Pedlar massif. Xenoliths of older rock are found in the Roses Mill pluton. Age is Middle Proterozoic, based on a U-Pb date of 970 Ma.
