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.
All rocks are made of minerals. Igneous rocks are formed from molten and magma eg. basalt and granite, Sedimentary rocks are mechanically or organically formed eg. sandstone, â¦ limestone and shale and Metamorphic rocks are formed from igneous or sedimentary rocks altered by heat or pressure eg. slate and graphite.here are a lot of processes involved that transform a sedimentary rock into an igneous or metamorphic rock. But in short detail a sedimentary rock becomes metamorphic when it â¦ is exposed to pressure and or heat.
