Explanation:
Quartzite
is use for making bricks and other strong building materials. It is also growing in popularity as a decorative stone, and has a limited use as crushed stone. As it is so hard, quartzite is not quarried as much as softer stone, and tends to be taken from the surface rather than underground.
Limestone
is used extensively in road and building construction, and is a material found in aggregate, cement, building stones, chalk, and crushed stone.

Slabs and blocks of marble are used for stair treads, floor tiles, facing stone, cemetery stones, window sills, ashlars, sculptures, benches, paving stones and many other uses.
