It doesn't. Granite is an igneous rock, not metamorphic. However, quartzite is metamorphic and is made from sandstone.
A schist rock belongs in the metamorphic rock group.
Quartzite comes under the metamorphic section of rocks.
Lime stone (the only mineral is calcite CaCO3 and belong to group carbonate), and the second example is halite( the only mineral is halite, composition is Nacl and belong to evaporates group).

Quartzite is a metamorphic rock formed from sandstone. The process involves heat and pressure altering the sandstone's mineral composition, causing quartz grains to recrystallize and fuse together, resulting in a harder, more durable rock. Quartzite is known for its smooth texture, high resistance to weathering, and distinctive white color.
