amphibolite | rock | Britannica

amphibolite, a rock composed largely or dominantly of minerals of the amphibole group The term has been applied to rocks of either igneous or metamorphic origin In igneous rocks, the term hornblendite is more common and restrictive; hornblende is the most common amphibole and is typical of such rocks Hornblendite is an ultramafic rock (dominantly dark minerals)A garnet amphibolite from the Imjingang belt in the Korean Peninsula is chosen as an example of the PTt estimation for metamorphic rocks with an upper amphibolite facies peak metamorphism (Fig 10; Lee et al, 2019) The Imjingang belt has been suggested as an extension of the DabieSulu collision belt in China but gives PT conditions of upper amphibolite facies metamorphism instead of theAmphibolite an overview | ScienceDirect Topics
