Formation

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

Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

All about Limestone and Rhyolite Properties

Know all about Limestone and Rhyolite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Rhyolite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Rhyolite is Aphanitic, Glassy, Porphyritic. Limestone appears Rough and Banded and Rhyolite appears Banded. The luster of Limestone is dull to pearly while that of Rhyolite is earthy. 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 Rhyolite is available in grey, white, light black 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 Rhyolite are gemstone, laboratory bench tops, jewelry.
