Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

All about Limestone and Anorthosite Properties
Know all about Limestone and Anorthosite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Anorthosite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Anorthosite is Foliated, Glassy. Limestone appears Rough and Banded and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Limestone is dull to pearly while that of Anorthosite is pearly to subvitreous. 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 Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white 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 Anorthosite are creating artwork, curling.
