Triple oxygen isotopes in meteoric waters, carbonates, and biological apatites: implications for continental paleoclimate reconstruction
The usefulness of triple isotope studies of natural systems is contingent on the existence of
resolvable differences in mass-dependent fractionation exponents θ [where θ= ln (17/16α)/ln …

Standardization for the triple oxygen isotope system: Waters, silicates, carbonates, air, and sulfates
Stable isotope analyses are a relative measurement. The precision is far higher than the
accuracy, so that subtle isotopic differences must be made relative to a reference. Modern …
