Formation

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

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.

All about Limestone and Amphibolite Properties

Know all about Limestone and Amphibolite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Amphibolite belongs to Metamorphic Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Amphibolite is Banded, Foliated, Massive. Limestone appears Rough and Banded and Amphibolite appears Foliated. The luster of Limestone is dull to pearly while that of Amphibolite is vitreous to dull. Limestone and Amphibolite are 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 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 and that of Amphibolite are cemetery markers, commemorative tablets, creating artwork.
