Quartzite The main mineral is quartz, which may contain mica minerals, hematite, goethite, etc.Quartzite is a metamorphic rock mainly composed of quartz (quartz content is more than 85%), which is formed by the metamorphism of quartz sandstone and siliceous rock. It is generally formed by recrystallization of quartz sandstone or other siliceous rocks through regional metamorphism. It is also possible that siliceous rocks near the magma undergo thermal contact metamorphism to form quartzite.
