Diorite and Limestone
Definition
Definition
Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms 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.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

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