Metamorphism of Mafic Rocks SpringerLink
Metamorphic mafic rocks (e.g. mafic schists and gneisses, amphibolites) are derived from mafic igneous rocks, mainly basalts and andesites, and of lesser importance, gabbros (Chap. 2). Metamorphic assemblages found in mafic rocks are used to define the intensity of metamorphism in the metamorphic facies concept (Chap. 4).

Regional metamorphic rock results from regional metamorphism and usually develops a flaky texture. It is distributed most widely in metamorphic rock, from Archean to even Cenozoic. In view of formation time, space, and acting mechanism, the regional metamorphic rock is closely related to the crustal orogeny and great tectonic movement.
