Formation
Pyrolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Pyrolite vs Phonolite 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. Pyrolite vs Phonolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyrolite and Properties of Phonolite. Learn more about Pyrolite vs Phonolite in the next section. The interior uses of Pyrolite include Decorative aggregates and Interior decoration whereas the interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Pyrolite and Phonolite, they have various applications in construction industry. The uses of Pyrolite in construction industry include As dimension stone, Cobblestones and that of Phonolite 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.
More about Pyrolite and Phonolite
Here you can know more about Pyrolite and Phonolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyrolite and Phonolite consists of mineral content and compound content. The mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Pyrolite vs Phonolite, the texture, color and appearance plays an important role in determining the type of rock. Pyrolite is available in dark greenish - grey colors whereas, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Pyrolite is Rough and Shiny and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Pyrolite vs Phonolite. Hardness of Pyrolite and Phonolite is 5.5-6. The types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite 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 Pyrolite and Phonolite is white. The specific heat capacity of Pyrolite is 1.25 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.Pyrolite is heat resistant, pressure resistant, wear resistant whereas Phonolite is heat resistant, impact resistant, wear resistant.
