5.1 Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

All about Limestone and Pyroxenite Properties

Know all about Limestone and Pyroxenite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Pyroxenite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Pyroxenite is Clastic, Granular, Phaneritic, Porphyritic. Limestone appears Rough and Banded and Pyroxenite appears Layered, Banded, Veined and Shiny. The luster of Limestone is dull to pearly while that of Pyroxenite is dull to vitreous to submetallic. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey 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 Pyroxenite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
