A sandstone with at least 25 percent feldspar is called arkose. A sandstone made of volcanic particles is called tuff. The cement in sandstone is usually one of three materials: silica (chemically the same as quartz), calcium carbonate or iron oxide.
No. Sandstone is sedimentary rock, where the individual grains of sand that compose the rock are visible without magnification. These individual grains of sand (sediment) have â¦ become compacted and cemented together in a process called lithification, forming a sedimentary rock.Metamorphic rock can be formed from virtually any parent rock (protolith) that has been subjected to heat and/or pressure, modifying its texture or mineral composition.Quartz sandstone, when metamorphosed, becomes the metamorphic rock 'quartzite'. rock formed by the metamorphism (addition of high temperature and pressure) of sandstone would be quartzite.
