English name: quartzite (aventurine quartzite). Mineral (rock) name: quartzite, the main mineral is quartz, which can contain mica minerals, hematite, goethite and so on. Quartzite is a metamorphic rock composed mainly of quartz (quartzite content greater than 85%), which is formed by metamorphism of quartz sandstone and siliceous rock.

It is also possible that siliceous rocks near the magma form quartzite by thermal contact metamorphism.
