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

Mineral bands in metamorphic rocks have light and dark colors due to differences in mineral composition and crystal structure. Light-colored bands may contain minerals like quartz and feldspar, which are commonly lighter in color, while dark-colored bands may have minerals like biotite or amphibole, which are darker in color. These variations result from the specific conditions of pressure, temperature, and chemical composition during the rock's formation.

Why are some igneous rock dark and other light?

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.
