Definition
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

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 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 Wehrlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Wehrlite. Learn more about Quartzite vs Wehrlite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Wehrlite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Quartzite and Wehrlite, 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 Wehrlite include As dimension stone, Cobblestones.
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 Not Available whereas types of Wehrlite are Not Available. 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.
