Formation

Formation

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Lherzolite 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 vs Lherzolite 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 Quartzite and Lherzolite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions. 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 Quartzite vs Lherzolite information and Quartzite vs Lherzolite characteristics in the upcoming sections.

Quartzite vs Lherzolite 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. Quartzite vs Lherzolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Lherzolite. Learn more about Quartzite vs Lherzolite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Lherzolite include Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Quartzite and Lherzolite, they have various applications in construction industry. The uses of Quartzite in construction industry 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 and that of Lherzolite include Landscaping, Manufacture of magnesium and dolomite refractories, Used for flooring, stair treads, borders and window sills..

More about Quartzite and Lherzolite

Here you can know more about Quartzite and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Lherzolite consists of mineral content and compound content. The mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Lherzolite, the texture, color and appearance plays an important role in determining the type of rock. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Quartzite is Lustrous and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Quartzite vs Lherzolite. The hardness of Quartzite is 6-7 and that of Lherzolite is 6.5. The types of Quartzite are Orthoquartzite and Metaquartzite whereas types of Lherzolite are Garnet Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite and Lherzolite is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Lherzolite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant.
