The amphibole constitutes 50 percent or more of the total mafic constituents and is present in an amount of 30 percent or more; other common minerals include quartz, clinopyroxene, garnet, epidote-group minerals, biotite, titanite and scapolite.en2015-08-18 18:02 PM CESThttp://inspire.ec.europa.eu/codelist/LithologyValue/chloriteActinoliteEpidoteMetamorphicRock:1http://inspire.ec.europa.eu/codelist/LithologyValue/chloriteActinoliteEpidoteMetamorphicRockMetamorphic rock characterized by 50 percent or more of combined chlorite, actinolite and epidote.
