5.1 Formation

Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

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

Anorthosite 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 Anorthosite and Quartzite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. 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 Anorthosite vs Quartzite information and Anorthosite vs Quartzite characteristics in the upcoming sections.

More about Anorthosite and Quartzite

Here you can know more about Anorthosite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Quartzite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene 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 Anorthosite vs Quartzite, the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Quartzite is Lustrous. Properties of rock is another aspect for Anorthosite vs Quartzite. The hardness of Anorthosite is 5-6 and that of Quartzite is 6-7. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Quartzite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Quartzite is white. The specific heat capacity of Anorthosite 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.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
