Archaeological Significance
Formation
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.
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 Anorthosite and Whiteschist
Here you can know more about Anorthosite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Whiteschist consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene 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 Anorthosite vs Whiteschist, the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Whiteschist is available in green, grey, white colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Anorthosite vs Whiteschist. The hardness of Anorthosite is 5-6 and that of Whiteschist is 1.5. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite 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 Anorthosite and Whiteschist is white. The specific heat capacity of Anorthosite 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.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Whiteschist is heat resistant.
