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

Formation
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.
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 Whiteschist and Eclogite
Here you can know more about Whiteschist and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Eclogite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica 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 Metamorphic Rocks. When we have to compare Whiteschist vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in colourless, green, grey, white colors whereas, Eclogite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Whiteschist is Banded and Foilated and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Whiteschist vs Eclogite. The hardness of Whiteschist is 1.5 and that of Eclogite is 3.5-4. The types of Whiteschist are Not Available whereas types of Eclogite are Not Available.
