Mass fractionation laws, mass-independent effects, and isotopic anomalies
N Dauphas, EA Schauble - Annual Review of Earth and …, 2016 - annualreviews.org
Isotopic variations usually follow mass-dependent fractionation, meaning that the relative
variations in isotopic ratios scale with the difference in mass of the isotopes involved (eg …

Triple oxygen isotopes in the water cycle
The past decade has seen a remarkable expansion of studies that use mass-dependent
variations of triple oxygen isotopes (16 O, 17 O, 18 O) in isotope hydrology and isotope …

A calibration of the triple oxygen isotope fractionation in the SiO2–H2O system and applications to natural samples
ZD Sharp, JA Gibbons, O Maltsev, V Atudorei… - … et Cosmochimica Acta, 2016 - Elsevier
It is now recognized that variations in the Δ 17 O of terrestrial materials resulting from purely
mass dependent fractionations, though small, have geological significance. In this study, the …

Oxygen isotopic evidence for vigorous mixing during the Moon-forming giant impact
Earth and the Moon are shown here to have indistinguishable oxygen isotope ratios, with a
difference in Δ′ 17O of− 1±5 parts per million (2 standard error). On the basis of these data …

Oxygen isotope identity of the Earth and Moon with implications for the formation of the Moon and source of volatiles
The Moon formed 4.5 Ga ago through a collision between proto-Earth and a planetesimal
known as Theia. The compositional similarity of Earth and Moon puts tight limits on the …
