Amphibolite: Metamorphic Rock
What is Amphibolite? Amphibolite is a coarse-grained metamorphic rock that is composed mainly of green, brown, or black amphibole minerals and plagioclase feldspar.The amphiboles are usually members of the hornblende group. It can also contain minor amounts of other metamorphic minerals such as biotite, epidote, garnet, wollastonite, andalusite, staurolite, …

Similarly, the starting amphibolite (PC-227) used in the experiments of Adam et al.
