Contact and regional metamorphism.

Explanation:

Contact metamorphism occurs when igneous rock cooks the surrounding metamorphic rock. Usually, magma comes in contact with metamorphic rock, which will subsequently change the minerals and textures of the rock.

Regional metamorphism occurs when metamorphic rock is subjected to high temperatures and pressures. The rock is cooked as it becomes more dense.

In both instances, mineral grains shape into the metamorphic rocks' notable patterns.
