A raw material is something that is not made up of something else.

The formation and transformation of principal categories of rocks, igneous, sedimentary, and metamorphic, are natural processes that are also known as rock cycle.

Hence, pre-existing types of rocks can suffer transformation processes, such as hydrothermalism or fault slip, that lead to formation of metamorphic rocks.

The process of fragmentation of igneous, sedimentary, and metamorphic rocks can lead to formation of sedimentary rocks.

The melting process of principal categories of rocks can lead to formation of igneous rocks.

Hence, as a conclusion, different natural processes, such as volcanism, erosion, sediment transportation, sediment burial etc., can transform pre-existing rocks, belonging to principal described categories, into new rocks.
