Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

More about Whiteschist and Limestone
Here you can know more about Whiteschist and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Limestone consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Limestone, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in green, grey, white colors whereas, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Whiteschist is Banded and Foilated and that of Limestone is Rough and Banded. Properties of rock is another aspect for Whiteschist vs Limestone. The hardness of Whiteschist is 1.5 and that of Limestone is 3-4. The types of Whiteschist are - whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Whiteschist and Limestone is white. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K and that of Limestone is 0.91 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 Limestone is pressure resistant.
