Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Teschenite 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 Teschenite 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 Teschenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Teschenite. Learn more about Quartzite vs Teschenite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Teschenite include Countertops, Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Quartzite and Teschenite, 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 Teschenite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Quartzite and Teschenite
Here you can know more about Quartzite and Teschenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Teschenite 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 Teschenite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Teschenite, 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, Teschenite is available in dark grey to black colors. Appearance of Quartzite is Lustrous and that of Teschenite is Veined and Shiny. Properties of rock is another aspect for Quartzite vs Teschenite. The hardness of Quartzite is 6-7 and that of Teschenite is 7. The types of Quartzite are Not Available whereas types of Teschenite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite is white while that of Teschenite is black. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Teschenite is Not Available. 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 Teschenite is impact resistant, pressure resistant, wear resistant.
