Formation
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
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 Andesite and Whiteschist
Here you can know more about Andesite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Whiteschist consists of mineral content and compound content. The mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon and mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Andesite vs Whiteschist, the texture, color and appearance plays an important role in determining the type of rock. Andesite is available in bluish - grey, grey, pink, yellow colors whereas, Whiteschist is available in colourless, green, grey, white colors. Appearance of Andesite is Dull and Soft and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Andesite vs Whiteschist. The hardness of Andesite is 7 and that of Whiteschist is 1.5. The types of Andesite are Icelandite 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 Andesite and Whiteschist is white. The specific heat capacity of Andesite is 2.39 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.Andesite is heat resistant, pressure resistant, wear resistant whereas Whiteschist is heat resistant.
