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.
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

All about Amphibolite and Rhyolite Properties

Know all about Amphibolite and Rhyolite properties here. All properties of rocks are important as they define the type of rock and its application. Amphibolite belongs to Metamorphic Rocks while Rhyolite belongs to Igneous Rocks.Texture of Amphibolite is Banded, Foliated, Massive whereas that of Rhyolite is Aphanitic, Glassy, Porphyritic. Amphibolite appears Foliated and Rhyolite appears Banded. The luster of Amphibolite is vitreous to dull while that of Rhyolite is earthy. Amphibolite is available in black, brown, green, grey colors whereas Rhyolite is available in grey, white, light black colors. The commercial uses of Amphibolite are cemetery markers, commemorative tablets, creating artwork and that of Rhyolite are gemstone, laboratory bench tops, jewelry.
