  • Mass-independent isotope fractionation or Non-mass-dependent fractionation (​NMD), refers to any chemical or physical process that acts to separate isotopes.

    Isotopic variations usually follow mass-dependent fractionation, meaning ations that follow a slope-one line (δ17O ≈ δ18O) whose origin. Abstract—The mass-dependent fractionation laws that describe the partitioning of isotopes such terrestrial mass fractionation lines are used as indicators of.
