The Rock Cycle

Sedimentary rocks like bituminous coal, limestone, and sandstone, given enough heat and pressure, can turn into nonfoliated metamorphic rocks like anthracite coal, marble, and quartzite. Nonfoliated rocks can also form by metamorphism, which happens when magma comes in contact with the surrounding rock.

Quartzite: properties, composition, mining, quartzite in the interior

It is a metamorphic rock composed primarily of quartz, one of the most abundant minerals in the Earth's crust. Quartzite was formed by metamorphism (structural change under high temperature and pressure) from siliceous sediments. Most often its formation is due to recrystallization of quartz sandstones or igneous rocks, such as …

Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Quartzite is 6-7 whereas its compressive strength is 115.00 N/mm 2. Streak is the color of rock when it is crushed or powdered.

Quartzite

Quartzite is a compact, hard, nonfoliated, medium to coarsely crystalline, and almost mono mineral metamorphic rocks with granoblastic texture. The isometric grain shape and their jagged contacts are a consequence of the process of recrystallization and loss of primary forms and contacts of grain under high pressure and high-temperature conditions.
