Archaeological Significance
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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

More about Whiteschist and Laterite
Here you can know more about Whiteschist and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Laterite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in green, grey, white colors whereas, Laterite is available in brown, buff, red colors. Appearance of Whiteschist is Banded and Foilated and that of Laterite is Rough and Banded. Properties of rock is another aspect for Whiteschist vs Laterite. The hardness of Whiteschist is 1.5 and that of Laterite is 2. The types of Whiteschist are - whereas types of Laterite are Laterite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Whiteschist and Laterite is white. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K and that of Laterite is 0.92 kJ/Kg K.
