A crystal of a solid solution shows compositional zoning when its composition varies from core to rim, recording the changing liquid from which successive layers grew. Zoning is normal when the rim is richer in the low-temperature component (sodium in plagioclase), reverse when it is richer in the high-temperature one, and oscillatory when it alternates.
