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.

Limestone vs Eclogite 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. Limestone vs Eclogite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Eclogite. Learn more about Limestone vs Eclogite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Eclogite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Limestone and Eclogite, they have various applications in construction industry. The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Eclogite include .
More about Limestone and Eclogite
Here you can know more about Limestone and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Eclogite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite. You can also check out the list of all Sedimentary Rocks. When we have to compare Limestone vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. 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, green, grey, pink, white colors. Appearance of Limestone is Rough and Banded and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Limestone vs Eclogite. The hardness of Limestone is 3-4 and that of Eclogite is 3.5-4. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Eclogite are Eclogite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Limestone and Eclogite is white. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Eclogite is 0.75 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Limestone is pressure resistant whereas Eclogite is heat resistant.
