Formation

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

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Phonolite vs Quartzite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Phonolite and Quartzite Reserves. Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Phonolite vs Quartzite information and Phonolite vs Quartzite characteristics in the upcoming sections.

More about Phonolite and Quartzite

Here you can know more about Phonolite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phonolite and Quartzite 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 Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Phonolite vs Quartzite, 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, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Phonolite is Banded and Foilated and that of Quartzite is Lustrous. Properties of rock is another aspect for Phonolite vs Quartzite. The hardness of Phonolite is 5.5-6 and that of Quartzite is 6-7. The types of Phonolite are Kenyte whereas types of Quartzite are Orthoquartzite and Metaquartzite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Phonolite and Quartzite is white. The specific heat capacity of Phonolite is 0.84 kJ/Kg K and that of Quartzite is 0.75 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
