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.

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Amphibolite and Limestone Properties

Know all about Amphibolite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Amphibolite belongs to Metamorphic Rocks while Limestone belongs to Sedimentary Rocks.Texture of Amphibolite is Banded, Foliated, Massive whereas that of Limestone is Clastic or Non-Clastic. Amphibolite appears Foliated and Limestone appears Rough and Banded. The luster of Amphibolite is vitreous to dull while that of Limestone is dull to pearly. Amphibolite is available in black, brown, green, grey colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Amphibolite are cemetery markers, commemorative tablets, creating artwork and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
