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

Theralite 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. Theralite vs Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Theralite and Properties of Quartzite. Learn more about Theralite vs Quartzite in the next section. The interior uses of Theralite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Theralite and Quartzite, they have various applications in construction industry. The uses of Theralite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate 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 Theralite and Quartzite
Here you can know more about Theralite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Theralite and Quartzite consists of mineral content and compound content. The mineral content of Theralite includes Augite, Olivine, 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 Theralite vs Quartzite, the texture, color and appearance plays an important role in determining the type of rock. Theralite is available in dark grey to black colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Theralite is Veined and Shiny and that of Quartzite is Lustrous. Properties of rock is another aspect for Theralite vs Quartzite. The hardness of Theralite is 7 and that of Quartzite is 6-7. The types of Theralite are Teschenite and Essexite 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 Theralite and Quartzite is white. The specific heat capacity of Theralite is 0.74 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.Theralite is impact resistant, pressure resistant, wear resistant whereas Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
