WebCumulate layering. Wager and Brown (1968) discuss the use of the term “banding” and “layering” and suggest that banding should be used for any streaky or roughly planar heterogeneity in igneous rocks, the term layering being reserved for sheet-like structures produced by crystal settling. Cumulate layers show many similarities to ... Fractional crystallization, or crystal fractionation, is one of the most important geochemical and physical processes operating within crust and mantle of a rocky planetary body, such as the Earth. It is important in the formation of igneous rocks because it is one of the main processes of magmatic differentiation.
