Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Peridotite vs Quartzite 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. Peridotite vs Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Quartzite. Learn more about Peridotite vs Quartzite in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Peridotite and Quartzite, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.
More about Peridotite and Quartzite
Here you can know more about Peridotite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Quartzite consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene 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 Peridotite vs Quartzite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Peridotite is Rough and Shiny and that of Quartzite is Lustrous. Properties of rock is another aspect for Peridotite vs Quartzite. The hardness of Peridotite is 5.5-6 and that of Quartzite is 6-7. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite 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 Peridotite and Quartzite is white. The specific heat capacity of Peridotite is 1.26 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.Peridotite is heat resistant, pressure resistant, wear resistant whereas Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
