Formation

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

Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

All about Limestone and Diorite Properties

Know all about Limestone and Diorite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Diorite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Diorite is Phaneritic. Limestone appears Rough and Banded and Diorite appears Shiny. The luster of Limestone is dull to pearly while that of Diorite is shiny. 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 Diorite is available in black, brown, light to dark grey, 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 Diorite are creating artwork, curling.
