Amphibolite Metamorphic Rock Stock Photo Alamy Amphibolite is a coarse grained metamorphic rock, predominantly composed of mineral amphibole and plagioclase feldspar. it can also contain minor amounts of other metamorphic minerals such as biotite, epidote, garnet, wollastonite, andalusite, staurolite, kyanite, and sillimanite. The chemical compositions of constituent minerals are the same in both garnetite and garnet amphibolite. the metamorphic p–t conditions of these rocks were estimated by thermodynamic calculations. The chemical compositions of constituent minerals are the same in both garnetite and garnet amphibolite. the metamorphic p–t conditions of these rocks were estimated by thermodynamic. First, for an ortho amphibolite or amphibolite to be classed as a metamorphic amphibolite, it must be certain that the amphibole in the rock is a prograde metamorphic product, and not a retrograde metamorphic product.

Debate abounds regarding the composition of the deep (middle lower) continental crust. exhumed medium and high grade metamorphic rocks, which range in composition from mafic to felsic, provide information about the bulk composition of the deep crust. 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. The blueschist facies is characterized in metabasites by the presence of a sodic blue amphibole stable only at high pressures (notably glaucophane, but some solution of crossite or riebeckite is possible). Om the meratus complex in south kalimantan, indonesia. eight varieties of metamorphic rocks samples from this location, which are garnet bearing epidote barroisite schist, epidote barroisite schist, glaucophane quartz schist, garnet muscovite schist, actinolite talc schist, epidote schist, muscovite schist, and serpentinite, were investigated.
