Archaeological Significance
Formation
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.
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 Pyroxenite and Whiteschist
Here you can know more about Pyroxenite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyroxenite and Whiteschist consists of mineral content and compound content. The mineral content of Pyroxenite includes Amphibole, Augite, Bronzite, Chromite, Diopside, Enstatite, Garnet, Hornblende, Hypersthene, Magnetite, 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 Pyroxenite vs Whiteschist, the texture, color and appearance plays an important role in determining the type of rock. Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors whereas, Whiteschist is available in green, grey, white colors. Appearance of Pyroxenite is Layered, Banded, Veined and Shiny and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Pyroxenite vs Whiteschist. The hardness of Pyroxenite is 7 and that of Whiteschist is 1.5. The types of Pyroxenite are Clinopyroxenites, Orthopyroxenites and Websterites 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 Pyroxenite and Whiteschist is white, greenish white or grey. The specific heat capacity of Pyroxenite is 0.84 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.Pyroxenite is impact resistant, pressure resistant, wear resistant whereas Whiteschist is heat resistant.
