Definition

Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz

Quartzite vs Adamellite 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 Adamellite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz. 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 Adamellite information and Quartzite vs Adamellite characteristics in the upcoming sections.

Quartzite vs Adamellite 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 Adamellite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Adamellite. Learn more about Quartzite vs Adamellite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Adamellite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Quartzite and Adamellite, 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 Adamellite include As dimension stone.

More about Quartzite and Adamellite

Here you can know more about Quartzite and Adamellite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Adamellite 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 Adamellite includes Apatite, Biotite, Chlorite, Orthoclase, Perthite, Plagioclase, Quartz, Titanite, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Adamellite, 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, Adamellite is available in black, grey, orange, pink, white colors. Appearance of Quartzite is Lustrous and that of Adamellite is Veined or Pebbled. Properties of rock is another aspect for Quartzite vs Adamellite. Hardness of Quartzite and Adamellite is 6-7. The types of Quartzite are Orthoquartzite and Metaquartzite whereas types of Adamellite are Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite and Adamellite is white. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Adamellite is 0.79 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 Adamellite is heat resistant, wear resistant.
