Crystal segregation
WebFractionation is an important petrogenetic process in the formation of cumulate carbonatites, the evolution of liquids that subsequently undergo immiscible separation, and the generation of residual liquids or fluids that are rare earth element (REE)-enriched ( Watkinson & Wyllie, 1971; Smith et al., 2016; Anenburg et al., 2024; Yaxley et al., … In some situations where segregation is important, the segregant atoms do not have sufficient time to reach their equilibrium level as defined by the above adsorption theories. The kinetics of segregation become a limiting factor and must be analyzed as well. Most existing models of segregation kinetics follow the McLean approach. In the model for equilibrium monolayer segregation, the solute atoms are assumed to segregate to a grain boundary from two infinite h…

( A) Iodide oxidation, reduction reaction, … 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. Fractional crystallization is also important in the formation of sedimentary evap…
