Eclogite vs Quartzite 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 Eclogite and Quartzite Reserves. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. 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 Eclogite vs Quartzite information and Eclogite vs Quartzite characteristics in the upcoming sections.

Eclogite 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. Eclogite vs Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Quartzite. Learn more about Eclogite vs Quartzite in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Eclogite and Quartzite, they have various applications in construction industry. The uses of Eclogite in construction industry include Not yet used 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 Eclogite and Quartzite

Here you can know more about Eclogite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Quartzite consists of mineral content and compound content.
