The rock cycle is a continuous process and does not stop after quartzite has formed. Quartzite is a metamorphic rock that forms when sandstone is subjected to high pressure and temperature. After quartzite has formed, it can undergo further changes through the processes of weathering, erosion, and deposition, which can break down the quartzite into sediments that can be recycled back into the rock cycle. These sediments can then be transformed into new sedimentary rocks, such as sandstone, which can then be subjected to metamorphism to form quartzite once again, or they can be transformed into other types of rocks through different geological processes.
