Mafic minerals typically include amphibole or mica; typically porphyritic. Includes rocks defined modally in QAPF fields 6, 7 and 8 (with subdivisions) or chemically in TAS Field T as trachyte or latite.en2015-08-18 18:01 PM CESThttp://inspire.ec.europa.eu/codelist/LithologyValue/alkaliFeldsparTrachyticRock:1http://inspire.ec.europa.eu/codelist/LithologyValue/alkaliFeldsparTrachyticRockTrachytoid that has a plagioclase to total feldspar ratio less than 0.1.
