Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Limestone and Benmoreite Properties
Know all about Limestone and Benmoreite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Benmoreite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Benmoreite is Glassy, Massive, Porphyritic, Scoriaceous, Trachytic, Vesicular. Limestone appears Rough and Banded and Benmoreite appears Rough and Dull. The luster of Limestone is dull to pearly while that of Benmoreite 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 Benmoreite is available in black, brown, light to dark 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 Benmoreite are commemorative tablets, creating artwork, curling.
