Archaeological Significance
Formation
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.
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 Foidolite and Whiteschist
Here you can know more about Foidolite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Whiteschist consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Foidolite vs Whiteschist, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, green, grey, pink, white colors whereas, Whiteschist is available in green, grey, white colors. Appearance of Foidolite is Dull and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Foidolite vs Whiteschist. Hardness of Foidolite and Whiteschist is 1.5. The types of Foidolite are Igneous rock 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 Foidolite and Whiteschist is white. The specific heat capacity of Foidolite is 0.79 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.Foidolite is heat resistant, wear resistant whereas Whiteschist is heat resistant.
