Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

All about Limestone and Basanite Properties
Know all about Limestone and Basanite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Basanite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Basanite is Aphanitic to Porphyritic. Limestone appears Rough and Banded and Basanite appears Glassy or Pearly. The luster of Limestone is dull to pearly while that of Basanite is waxy and dull. Limestone and Basanite 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 Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms.
