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.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

More about Whiteschist and Pumice
Here you can know more about Whiteschist and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Pumice consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Pumice, 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, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Whiteschist is Banded and Foilated and that of Pumice is Vesicular. Properties of rock is another aspect for Whiteschist vs Pumice. The hardness of Whiteschist is 1.5 and that of Pumice is 6. The types of Whiteschist are Not Available whereas types of Pumice are Scoria. 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 Pumice is white, greenish white or grey. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K and that of Pumice is 0.87 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 Pumice is impact resistant, pressure resistant.
