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

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

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