Formation

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

Wehrlite 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 Wehrlite 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 Wehrlite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites. 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 Wehrlite information and Quartzite vs Wehrlite characteristics in the upcoming sections.

More about Quartzite and Wehrlite

Here you can know more about Quartzite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Wehrlite 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 Wehrlite includes Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Wehrlite, 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, Wehrlite is available in dark greenish - grey, green colors. Appearance of Quartzite is Lustrous and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Quartzite vs Wehrlite. The hardness of Quartzite is 6-7 and that of Wehrlite is 5.5-6. The types of Quartzite are Orthoquartzite and Metaquartzite whereas types of Wehrlite are Ultramafic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite and Wehrlite is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Wehrlite is 0.63 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 Wehrlite is heat resistant, impact resistant, pressure resistant.
