Etymology
From French schiste, Greek skhistos i.e. split
From the Greek meaning sounding stone because of the metallic sound it produces if an unfractured plate is hit

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.
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

More about Whiteschist and Phonolite
Here you can know more about Whiteschist and Phonolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Phonolite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Phonolite, 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, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Whiteschist is Banded and Foilated and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Whiteschist vs Phonolite. The hardness of Whiteschist is 1.5 and that of Phonolite is 5.5-6. The types of Whiteschist are Not Available whereas types of Phonolite are Kenyte. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Whiteschist and Phonolite is white. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K and that of Phonolite is Not Available. 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 Phonolite is heat resistant, impact resistant, wear resistant.
