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.
Foidolites is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Whiteschist and Foidolite
Here you can know more about Whiteschist and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Foidolite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Foidolite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in green, grey, white colors whereas, Foidolite is available in black, brown, green, grey, pink, white colors. Appearance of Whiteschist is Banded and Foilated and that of Foidolite is Dull. Properties of rock is another aspect for Whiteschist vs Foidolite. Hardness of Whiteschist and Foidolite is 1.5. The types of Whiteschist are - whereas types of Foidolite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Whiteschist and Foidolite is white. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K and that of Foidolite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Whiteschist is heat resistant whereas Foidolite is heat resistant, wear resistant.
