Since many crustal magma source rocks apart from granites s l do not contain both feldspars it is not congruent melting at the wet granite solidus that we need to consider but rather the higher t h 2 o saturated melting of quartz and plagioclase and the h 2 o saturated melting reactions that involve mica and or amphibole breakdown.
Is granitic magma wet or dry.
It is important in the formation of igneous rocks because it is one of the main processes of magmatic differentiation.
Fractional crystallization or crystal fractionation is one of the most important geochemical and physical processes operating within crust and mantle of a rocky planetary body such as the earth.
Granitic or rhyolitic magmas and andesitic magmas are generated at convergent plate boundaries where the oceanic lithosphere the outer layer of earth composed of the crust and upper mantle is subducted so that its edge is positioned below the edge of the continental plate or.
