 · Quartzite. Quartzite is a metamorphic rock composed almost entirely from sandstone. The sandstone is altered by heat, immense pressure, and chemical activity. These conditions recrystallize the sand grains and the silica cement that bind them. The result is a network of interlocking quartz grains of incredible strength. Because it is so hard and dense, quartzite has not been quarried as ...

 · Metamorphic rocks are rocks that have changed from one type of rock to another. While sedimentary rock is formed from sediments, and igneous rock is formed from molten magma, metamorphic rock is rock made from preexisting rocks. These rocks undergo a change, either caused by high heat, high pressure, or exposure to mineral rich hot liquid, which transforms the existing rock .

Quartzite is a compact, hard, nonfoliated, medium to coarsely crystalline, and almost mono mineral metamorphic rocks with granoblastic texture. The isometric grain shape and their jagged contacts are a consequence of the process of recrystallization and loss of primary forms and contacts of grain under high pressure and hightemperature conditions.
