foliated.
The answer is foliated.
Mineral bands are light and dark colored because they are different types of rock. In the rock cycle different types of rock can stack on top of each other, this can be subducted into the earth near the Mantle where there is enough pressure the rocks can start to melt and change. Because different types of rock metamorphose into different rocks you can have many layers in a type of rock. These can be light or dark colors depending on the rock.
Foliated rock has parallel layers.
Foliated rock

That would be sedimentary rock, and (honorable mention) occasionally metamorphic rock.
