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.
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

More about Whiteschist and Dunite
Here you can know more about Whiteschist and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Dunite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Dunite, 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, Dunite is available in dark greenish - grey colors. Appearance of Whiteschist is Banded and Foilated and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Whiteschist vs Dunite. The hardness of Whiteschist is 1.5 and that of Dunite is 3.5-4. The types of Whiteschist are Not Available whereas types of Dunite are Not Available.
