Fractionation and Liquid Immiscibility in an Anorthositic Pluton of the Nain Complex, Labrador

Fine-grained anorthositic dikes are associated with a massive leuconorite pluton (Cl = 15) which is exposed over an area of about 200 km2. Internally, the pluton shows little compositional variation; average plagioclase composition ranges from An 52 to An 48 . The dikes are nearly uniform in composi...
