4 Formation
4.1 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.
Foidolites is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Amphibolite and Foidolite Properties

Know all about Amphibolite and Foidolite properties here. All properties of rocks are important as they define the type of rock and its application. Amphibolite belongs to Metamorphic Rocks while Foidolite belongs to Igneous Rocks.Texture of Amphibolite is Banded, Foliated, Massive whereas that of Foidolite is Earthy. Amphibolite appears Foliated and Foidolite appears Dull. The luster of Amphibolite is vitreous to dull while that of Foidolite is subvitreous to dull. Amphibolite is available in black, brown, green, grey colors whereas Foidolite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Amphibolite and Foidolite are cemetery markers, commemorative tablets, creating artwork.
