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.
Some marble also forms by contact metamorphism when a hot magma body heats adjacent limestone or dolostone. Before metamorphism, the calcite in the limestone is often in the form of lithified fossil material and biological debris. During metamorphism, this calcite recrystallizes and the texture of the rock changes.In the early stages of the limestone-to-marble transformation the calcite crystals in the rock are very small.efore metamorphism, the calcite in the limestone is often in the form of lithified fossil material and biological debris.
