Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism

Phyllite, Schist, and Slate
Features
High percentage of mica, Host Rock for Lead
Easily splits into thin plates, Surfaces are often shiny, Very fine grained rock
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.
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.

More about Whiteschist and Slate
Here you can know more about Whiteschist and Slate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Slate consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Slate includes Apatite, Biotite, Chlorite, Feldspar, Graphite, Hematite, Kaolinite, Magnetite, Pyrite, Tourmaline, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Slate, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in green, grey, white colors whereas, Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors. Appearance of Whiteschist is Banded and Foilated and that of Slate is Dull. Properties of rock is another aspect for Whiteschist vs Slate. The hardness of Whiteschist is 1.5 and that of Slate is 3-4. The types of Whiteschist are - whereas types of Slate are Phyllite, Schist, and Slate. 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 Slate is light to dark brown. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K and that of Slate is 0.76 kJ/Kg K.
