The geochemistry of differentiation process in granite magma chambers

Sawka, Wayne Nickolas


Three major, though interrelated, topics are addressed in this study and these are: 1) the crystal sorting mechanism in compositionally zoned granite plutons; 2) compositional variations in U-, Th- and rare-earth element concentrating accessory minerals; and, 3) the distribution of radioactive heat production in granites. Three examples of concentrically-zoned, I-type, granite plutons from the Sierra Nevada batholith, California, U.S.A., yield a consistent model for crystal fractionation...[Show more]
