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.

Eclogite vs Limestone Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Eclogite vs Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Limestone. Learn more about Eclogite vs Limestone in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Eclogite and Limestone, they have various applications in construction industry. The uses of Eclogite in construction industry include Not yet used and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.
More about Eclogite and Limestone
Here you can know more about Eclogite and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Limestone consists of mineral content and compound content. The mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Limestone, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, colourless, 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. Appearance of Eclogite is Dull, Banded and Foilated and that of Limestone is Rough and Banded. Properties of rock is another aspect for Eclogite vs Limestone. The hardness of Eclogite is 3.5-4 and that of Limestone is 3-4. The types of Eclogite are Not Available whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Limestone is white. The specific heat capacity of Eclogite is Not Available and that of Limestone is 0.91 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Eclogite is heat resistant whereas Limestone is pressure resistant.
