Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

Formation
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

More about Oolite and Eclogite
Here you can know more about Oolite and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Eclogite consists of mineral content and compound content. The mineral content of Oolite 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 Oolite vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas, Eclogite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Oolite is Rounded and Rough and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Oolite vs Eclogite. The hardness of Oolite is 3-4 and that of Eclogite is 3.5-4. The types of Oolite are Not Available whereas types of Eclogite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oolite and Eclogite is white. The specific heat capacity of Oolite is Not Available and that of Eclogite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Oolite is heat resistant, wear resistant whereas Eclogite is heat resistant.
