5 Formation

5.1 Formation

Picrite 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.

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

Picrite 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 Picrite and Quartzite Reserves. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. 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 Picrite vs Quartzite information and Picrite vs Quartzite characteristics in the upcoming sections.

More about Picrite and Quartzite

Here you can know more about Picrite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Picrite and Quartzite consists of mineral content and compound content. The mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite 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 Picrite vs Quartzite, the texture, color and appearance plays an important role in determining the type of rock. Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Picrite is Rough and Shiny and that of Quartzite is Lustrous. Properties of rock is another aspect for Picrite vs Quartzite. The hardness of Picrite is 6.8 and that of Quartzite is 6-7. The types of Picrite are Oceanite 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 Picrite and Quartzite is white, greenish white or grey. The specific heat capacity of Picrite is 0.88 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.Picrite is heat resistant whereas Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
