Answer:
Non-foliated, metamorphic, does not split into layers
Explanation:
Quartzite is a form of metamorphic rock that is non-foilated. It is formed when heat and pressure are induced in the sandstone rich in quartz. These factors help in the process of recrystallization of the sandstone which results in the formation of quartzite. Quartzite is characterized to be hard and durable rock. Because of the characteristic nature of toughness, it is used to make various tools.
