Rayleigh fractionation model
Websimplified model of isotopic fractionation in evaporation and condensation through the precipitation formation process. However, the slope of 8 and the d-value of 10 have not yet been correctly explained, and some modifi-cation of the Rayleigh distillation model is required for application to an actual precipitation forming process. WebOur model shows that methane oxidation cannot be described by traditional first-order kinetics. The kinetic isotope fractionation ceases when methane concentrations decrease …

WebIn other cases, the Δ value represents the isotope fractionation between the metal and the solid phase considered (coefficient of the slope in the whole range of the % of metal sorbed at equilibrium). Isotope data from higher percentages of adsorbed metal are needed to distinguish between an irreversible Rayleigh system and an equilibrium model. WebChemically zoned garnet growth and coeval modification of this zoning through diffusion are calculated during prograde metamorph-ic heating to temperatures of up to 8508C.This …
