WebRayleigh fractionation model that varies source and local temperature change to estimate the change in fraction of moisture remaining depending on local d18O of precipitation or … Rayleigh fractionation describes the evolution of a system with multiple phases in which one phase is continuously removed from the system through fractional distillation. It is used in particular to describe isotopic enrichment or depletion as material moves between reservoirs in an equilibrium process. … See more The original Rayleigh equation was derived by Lord Rayleigh for the case of fractional distillation of mixed liquids. This is an exponential relation that describes the partitioning of isotopes between two … See more • Isotope analysis See more dyschondrosteosis definition
