Quartzite is a metamorphic rock, that, in most cases, is 5,000 years old. Even thogh this rock is called Quartzite, it is not made from quartz. Instead, Quartzite is made from a form of limestone.
A quatzite and a marble
Two examples of non-foliated rocks are marble, which forms from the metamorphism of limestone, and quartzite, which forms from the metamorphism of sandstone. These rocks do not have a layered or banded appearance like foliated rocks such as schist or gneiss.
Quartzite is a metamorphic rock that is typically non-foliated, which means it does not have a layered or banded appearance like foliated rocks such as schist or gneiss. Quartzite forms through the metamorphism of sandstone and is composed mainly of quartz grains that have recrystallized under high pressure and temperature.
Quartzite is a metamorphic rock that is primarily used as a building material for countertops, tiles, and wall cladding due to its durability and attractive appearance. It is also used in construction for features like stair treads and sills. Additionally, quartzite is sometimes crushed and used as a road construction aggregate.
