Why are mineral bands in metamorphic rocks light and dark colored?
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.

The color of igneous rocks is determined by their mineral composition. Dark-colored igneous rocks, like basalt, contain minerals that are rich in iron and magnesium, which give them their dark appearance. Light-colored igneous rocks, like granite, tend to have higher concentrations of quartz and feldspar minerals, which are lighter in color. Overall, the mineral content and composition of the rock influence its color.
