Geochemical Classification for Granitic Rocks

Part of the problem in granite classification is that the same mineral assemblage, quartz and feldspars with a variety of ferromagnesian minerals, can be achieved by a number of processes. Granitoids can form from differentiation of any hypersthene-normative melt and from partial melting of many rock types.
