Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures

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.
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

More about Eclogite and Whiteschist
Here you can know more about Eclogite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Whiteschist 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 Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Whiteschist, 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, Whiteschist is available in green, grey, white colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Eclogite vs Whiteschist. The hardness of Eclogite is 3.5-4 and that of Whiteschist is 1.5. The types of Eclogite are Eclogite whereas types of Whiteschist are -. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Whiteschist is white. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Whiteschist 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 Whiteschist is heat resistant.
