Formation
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.
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 Shale and Whiteschist
Here you can know more about Shale and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Whiteschist consists of mineral content and compound content. The mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides and mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Sedimentary Rocks. When we have to compare Shale vs Whiteschist, the texture, color and appearance plays an important role in determining the type of rock. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Whiteschist is available in colourless, green, grey, white colors. Appearance of Shale is Muddy and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Shale vs Whiteschist. The hardness of Shale is 3 and that of Whiteschist is 1.5. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale whereas types of Whiteschist are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shale and Whiteschist is white. The specific heat capacity of Shale is 0.39 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.Shale is heat resistant, impact resistant whereas Whiteschist is heat resistant.
