Igneous rocks are classified according to their mineral content Ultramafic rocks are dominated by olivine andor pyroxene. Mafic rocks are dominated by plagioclase and pyroxene even if you cant see them with the naked eye and smaller amounts of olivine. Intermediate rocks are roughly even mixtures of felsic minerals mainly plagioclase and mafic minerals mainly hornblende, pyroxene ...
