Available in lots of colors, Generally rough to touch, Is one of the oldest rock
Archaeological Significance
Formation
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Sovites are formed due to low degrees of partial melting of rocks.

Phonolite vs Sovite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Phonolite vs Sovite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phonolite and Properties of Sovite. Learn more about Phonolite vs Sovite in the next section. The interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Sovite include Decorative aggregates and Homes. Due to some exceptional properties of Phonolite and Sovite, they have various applications in construction industry. The uses of Phonolite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics and that of Sovite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Phonolite and Sovite
Here you can know more about Phonolite and Sovite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phonolite and Sovite 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 Sovite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Phonolite vs Sovite, 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, Sovite is available in black, brown, green, grey, pink, white colors. Appearance of Phonolite is Banded and Foilated and that of Sovite is Dull, Banded and Foilated. Properties of rock is another aspect for Phonolite vs Sovite. The hardness of Phonolite is 5.5-6 and that of Sovite is 3. The types of Phonolite are Kenyte whereas types of Sovite are Carbonatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Phonolite and Sovite is white. The specific heat capacity of Phonolite is 0.84 kJ/Kg K and that of Sovite is 0.84 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 Sovite is heat resistant, pressure resistant.
