10. Origin of Granitoids Phase equilibria support either that granitoids are either the end product of fractional crystallization of a mafic parent or the partial melt generated from the melting of sialic crust - large corresponding extrusive equivalents suggests large magma chambers of equivalent composition. Field relations suggest that large plutons have diffuse boundaries and many seem to show variable and locally pervasive overprint of subsolidus recrystallization indicative of metamorphic origin.

15. Assessing States of Equilibrium Isolated anhedral grains that resulted from partial resorption or dissolution into the melt Reaction rims of one or more phases surrounding another anhedral crystalline phase. Compositionally zoned grains originate through incomplete reaction relations within a single solid solutions, e.g. plagioclase. Presence of minerals or a mineral assemblage that is known to be unstable or unlikely in an evolutionary sense, e.g. Mg-olivine and qtz together. Disequilibrium states are suggested by the following:
