Quartzite. Images: Background: Quartzite is a nonfoliated metamorphic rock that formed by the metamorphism of pure quartz sandstone. The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly intergrown with each other, resulting in very hard and dense quartzite.uartzite. Images: Background: Quartzite is a nonfoliated metamorphic rock that formed by the metamorphism of pure quartz sandstone. The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly intergrown with each other, resulting in very hard and dense quartzite. Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means change in form. The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (1500 bars), causing profound physical and/or chemical change.The protolith may be a sedimentary rock, an igneous rock or another older metamorphic rock.ther minerals, such as olivines, pyroxenes, amphiboles, micas, feldspars, and quartz, may be found in metamorphic rocks, but are not necessarily the result of the process of metamorphism. These minerals formed during the crystallization of igneous rocks. 1 Quartzite falls into the classification of a metamorphic rock. 2  Its original material, sandstone in this case, has been altered by pressure and heat that transforms it into quartzite.3  Buried deep inside the earth the sandstone adapts to the change in conditions by altering its texture and composition.

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. 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.Answered.etamorphic 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.

It can therefore be formed as an igneous rock by itself (rarely) and is part of many sedimentary rocks such as sandst … one. Quartz sandstone can also be metamorphosed into quartzite. Quartz can be found as part of any rock or by itself as a sediments. This small sample of Jotnian quartzite from Finland is either strongly cemented sandstone or weakly metamorphosed quartzite.

Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz. It forms when a quartz-rich sandstone, is altered by the heat, pressure, and chemical activity of metamorphism. These conditions recrystallize the sand grains and the silica cement that binds them together.uartzite is a nonfoliated metamorphic rock composed almost entirely of quartz.

It may be derived from sandstone or from chert by regional metamorphism. (more below). Quartzite forms in two different ways. In the first way, under the pressures and temperatures of deep burial, sandstone or chert recrystallizes resulting in a metamorphic rock.t may be derived from sandstone or from chert by regional metamorphism. (more below). Quartzite forms in two different ways. In the first way, under the pressures and temperatures of deep burial, sandstone or chert recrystallizes resulting in a metamorphic rock. 1 Quartzite is formed through two types of metamorphism: contact and Barrovian. 2  It can be formed by one of the processes or the other but it can also be formed by the combination of the two. 3  Barrovian metamorphism happens during large earth events that create mountains and move sedimentary rock in a big way. Its original material, sandstone in this case, has been altered by pressure and heat that transforms it into quartzite. 2  Buried deep inside the earth the sandstone adapts to the change in conditions by altering its texture and composition.
