Formation
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
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 Phonolite and Whiteschist
Here you can know more about Phonolite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phonolite and Whiteschist consists of mineral content and compound content. The mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite 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 Phonolite vs Whiteschist, the texture, color and appearance plays an important role in determining the type of rock. Phonolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Whiteschist is available in colourless, green, grey, white colors. Appearance of Phonolite is Banded and Foilated and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Phonolite vs Whiteschist. The hardness of Phonolite is 5.5-6 and that of Whiteschist is 1.5. The types of Phonolite are Kenyte 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 Phonolite and Whiteschist is white. The specific heat capacity of Phonolite is Not Available 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.Phonolite is heat resistant, impact resistant, wear resistant whereas Whiteschist is heat resistant.
