1 Definition

1.1 Definition

Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

5.1 Formation

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

Tachylite 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 Tachylite 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 Tachylite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. 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 Tachylite information and Quartzite vs Tachylite characteristics in the upcoming sections.

Quartzite vs Tachylite 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 Tachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Tachylite. Learn more about Quartzite vs Tachylite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Tachylite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Quartzite and Tachylite, 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 Tachylite include Cutting tool, Knives, Landscaping, Scrapers.

More about Quartzite and Tachylite

Here you can know more about Quartzite and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Tachylite 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 Tachylite includes Feldspar, Olivine. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Tachylite, 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, Tachylite is available in black, dark brown colors. Appearance of Quartzite is Lustrous and that of Tachylite is Glassy. Properties of rock is another aspect for Quartzite vs Tachylite. The hardness of Quartzite is 6-7 and that of Tachylite is 5.5. The types of Quartzite are Not Available whereas types of Tachylite 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 Tachylite is vermilion. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Tachylite is 0.56 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 Tachylite is heat resistant, impact resistant, wear resistant.
