WebJan 1, 2014 · The processes of differentiation and crystal fractionation within a magmatic body result in the chemical variations of solid and fluid phases. This change occurs from the alleged fluid-absent melting to water-saturated conditions, wherein the mantle derived plumes govern the nature of early fluid phase which subsequently may be built up by the ... WebJan 1, 2024 · Magmatic processes Magmas are commonly high-temperature silicate melts of wide compositional range from ultrabasic to acidic types, and generated by partial melting of upper mantle (e.g. McKenzie and Bickle, 1988) or crust (e.g. Annen et al., 2008 ).
