Archaeological Significance
Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
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 Granulite and Whiteschist
Here you can know more about Granulite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Whiteschist consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Whiteschist, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Whiteschist is available in green, grey, white colors. Appearance of Granulite is Veined or Pebbled and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Granulite vs Whiteschist. The hardness of Granulite is 6-7 and that of Whiteschist is 1.5. The types of Granulite are Metamorphic 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 Granulite and Whiteschist is white. The specific heat capacity of Granulite is 0.14 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.Granulite is heat resistant, wear resistant whereas Whiteschist is heat resistant.
