Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

More about Eclogite and Marble
Here you can know more about Eclogite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Marble 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 Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Marble is Veined and Shiny. Properties of rock is another aspect for Eclogite vs Marble. The hardness of Eclogite is 3.5-4 and that of Marble is 3-4. The types of Eclogite are Not Available whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Marble is white. The specific heat capacity of Eclogite is Not Available and that of Marble is 0.88 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 Marble is heat resistant.
