Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Etymology
From French, Greek eklogē selection with reference to the selective content of the rock + -ite1
From English clay and stone as the rock contains more amount of clay

Archaeological Significance
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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Eclogite vs Claystone 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 Claystone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Claystone. Learn more about Eclogite vs Claystone in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Eclogite and Claystone, they have various applications in construction industry. The uses of Eclogite in construction industry include and that of Claystone include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Eclogite and Claystone
Here you can know more about Eclogite and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Claystone 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 Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Claystone, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, green, grey, pink, white colors whereas, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Claystone is Rough and Dull. Properties of rock is another aspect for Eclogite vs Claystone. Hardness of Eclogite and Claystone is 3.5-4. The types of Eclogite are Eclogite whereas types of Claystone are Claystone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Claystone is white. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Claystone is 0.92 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 Claystone is heat resistant, impact resistant.
