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.
  
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 vs Anorthosite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Whiteschist vs Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Whiteschist and Properties of Anorthosite. Learn more about Whiteschist vs Anorthosite in the next section. The interior uses of Whiteschist include Decorative aggregates and Interior decoration whereas the interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Whiteschist and Anorthosite, they have various applications in construction industry. The uses of Whiteschist in construction industry include For road aggregate and that of Anorthosite include As dimension stone, Cement manufacture, For road aggregate.
More about Whiteschist and Anorthosite
Here you can know more about Whiteschist and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Anorthosite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in colourless, green, grey, white colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Whiteschist is Banded and Foilated and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Whiteschist vs Anorthosite. The hardness of Whiteschist is 1.5 and that of Anorthosite is 5-6. The types of Whiteschist are Not Available whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Whiteschist and Anorthosite is white. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K and that of Anorthosite is 0.84 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 Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
