Abstract
⺠Most models for chemical variation in granites are inadequate to account for the main variations. ⺠Many processes can play secondary roles but peritectic assemblage entrainment dominates. ⺠Partial melt may segregate from its residue carrying crystals of the peritectic assemblage. ⺠Peritectic crystals are entrained in a ratio decreed by the stoichiometry of the melting reaction. ⺠Thus, protolith composition is the primary control on granite magma chemistry.
