Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

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.
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.

More about Whiteschist and Shale
Here you can know more about Whiteschist and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Shale consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all . When we have to compare Whiteschist vs Shale, 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, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Whiteschist is Banded and Foilated and that of Shale is Muddy. Properties of rock is another aspect for Whiteschist vs Shale. The hardness of Whiteschist is 1.5 and that of Shale is 3. The types of Whiteschist are Not Available whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Whiteschist and Shale is white. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K and that of Shale is 0.39 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 Shale is heat resistant, impact resistant.
