This metamorphic rocks name is Morbal. This rock is mostly used to me by seeing art.

Amphibolite

This is a non-foliated metamorphic rock that forms through recrystallization under conditions of high viscosity and directed pressure.

This sedimatary rocks name is iron ore. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters.

This sedimentary rocks name is coal. Organic sedimentary rock that forms mainly from plant debris. The plant debris usually accumulates in a swamp environment.
