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.
Igneous rocks are formed when magma or lava cools and hardens. An igneous rock becomes a sedimentary rock through weathering and erosion of the igneous rock. The igneous rock, exposed to weathering processes at the surface, breaks into smaller pieces.nce cemented together, it is now considered sedimentary rock. Igneous rocks become metamorphic rocks once it has undergone metamorphism. Metamorphism is the change in form of a geological unit (like a rock) through metamorphic processes (must be in solid state).
