Definition
Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks

Formation
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

Phonolite vs Phyllite 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 Phyllite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phonolite and Properties of Phyllite. Learn more about Phonolite vs Phyllite in the next section. The interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Phyllite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Phonolite and Phyllite, 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 Phyllite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar, Roadstone.
More about Phonolite and Phyllite
Here you can know more about Phonolite and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phonolite and Phyllite 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 Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon. You can also check out the list of all . When we have to compare Phonolite vs Phyllite, 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, Phyllite is available in black to grey, light greenish grey colors. Appearance of Phonolite is Banded and Foilated and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Phonolite vs Phyllite. The hardness of Phonolite is 5.5-6 and that of Phyllite is 1-2. The types of Phonolite are Kenyte whereas types of Phyllite 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 Phyllite is white. The specific heat capacity of Phonolite is Not Available and that of Phyllite is Not Available. 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 Phyllite is heat resistant, pressure resistant, water resistant.
