Quartzite. Quartzite is a metamorphic rock consisting largely or entirely of quartz. In vast majority of cases, quartzite is a metamorphosed sandstone. The transition from sandstone to quartzite is gradational. There is little mineralogical change.Quartz, the main constituent of sandstone, is not altered to other minerals but it is recrystallized during the metamorphism.his small sample of Jotnian quartzite from Finland is either strongly cemented sandstone or weakly metamorphosed quartzite. It is old (1.4 Ga) and a part of crystalline basement. Hence, it is usually considered to be a metamorphic rock. Width of the sample is 4 cm.
Gneiss can be formed from a sedimentary rock such as sandstone or shale, or it can be formed from the metamorphism of the igneouse rock grantite. Gneiss can be used by man as paving and building stone. Quartzite is composed of sandstone that has been metamorphosed. Quartzite is much harder than the parent rock, sandstone. It forms from sandstone that has come into contact with deeply buried magmas. Quartzite looks similar to its parent rock. The best way to tell quartzite from sandstone is to break the rocks.
