5 Formation

5.1 Formation

Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

All about Amphibolite and Peridotite Properties

Know all about Amphibolite and Peridotite properties here. All properties of rocks are important as they define the type of rock and its application. Amphibolite belongs to Metamorphic Rocks while Peridotite belongs to Igneous Rocks.Texture of Amphibolite is Banded, Foliated, Massive whereas that of Peridotite is Phaneritic. Amphibolite appears Foliated and Peridotite appears Rough and Shiny. The luster of Amphibolite is vitreous to dull while that of Peridotite is shiny. Amphibolite is available in black, brown, green, grey colors whereas Peridotite is available in dark greenish - grey colors. The commercial uses of Amphibolite are cemetery markers, commemorative tablets, creating artwork and that of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
