Quartzite is a metamorphic rock that is formed from the sedimentary rock sandstone. Slate is a metamorphic rock that is formed from the sedimentary rock mudstone. Granulite is a metamorphic rock that is formed from the igneous rock basalt.
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'.1 person found this useful.uartz is a mineral composed of Silicon Dioxide (SiO2). It can therefore be formed as an igneous rock by itself (rarely) and is part of many sedimentary rocks such as sandst â¦ one. Quartz sandstone can also be metamorphosed into quartzite. Quartz can be found as part of any rock or by itself as a sediments.
