Limestone and Eclogite
Definition
Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

All about Limestone and Eclogite Properties
Know all about Limestone and Eclogite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Eclogite belongs to Metamorphic Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Eclogite is Earthy. Limestone appears Rough and Banded and Eclogite appears Dull, Banded and Foilated. The luster of Limestone is dull to pearly while that of Eclogite is subvitreous to dull. 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 Eclogite is available in black, brown, colourless, green, 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 Eclogite are creating artwork, gemstone.
