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.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

More about Whiteschist and Diorite
Here you can know more about Whiteschist and Diorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Diorite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Diorite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in green, grey, white colors whereas, Diorite is available in black, brown, light to dark grey, white colors. Appearance of Whiteschist is Banded and Foilated and that of Diorite is Shiny. Properties of rock is another aspect for Whiteschist vs Diorite. The hardness of Whiteschist is 1.5 and that of Diorite is 6-7. The types of Whiteschist are - whereas types of Diorite are Plagioclase Diorite and Quartz Diorite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Whiteschist is white while that of Diorite is bluish black. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K and that of Diorite is 0.84 kJ/Kg K.
