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.
Latite 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 Latite Properties
Know all about Amphibolite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Amphibolite belongs to Metamorphic Rocks while Latite belongs to Igneous Rocks.Texture of Amphibolite is Banded, Foliated, Massive whereas that of Latite is Aphanitic to Porphyritic. Amphibolite appears Foliated and Latite appears Rough. The luster of Amphibolite is vitreous to dull while that of Latite is subvitreous to dull. Amphibolite is available in black, brown, green, grey colors whereas Latite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Amphibolite are cemetery markers, commemorative tablets, creating artwork and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
