Journal ArticleDOI
Spinel–olivine magnesium isotope thermometry in the mantle and implications for the Mg isotopic composition of Earth
TL;DR: In this paper, the authors present new high-precision 25 Mg/24 Mg measurements of mantle minerals and compare these ratios with predictions for temperature-dependent inter-mineral fractionations.
Journal ArticleDOI
High-temperature equilibrium isotope fractionation of non-traditional stable isotopes: Experiments, theory, and applications
Edward D. Young,Craig E. Manning,Edwin A. Schauble,Anat Shahar,Catherine A. Macris,Codi Lazar,M. K. Jordan +6 more
TL;DR: In this paper, the fundamental driving forces for equilibrium inter-mineral fractionation comes from basic crystal chemistry and is invaluable for interpreting data from natural systems, which relies on refinements of equilibrium fractionation factors through a feedback between crystal chemical reasoning, ab initio predictions, experiments, and analyses of well-characterized natural samples.
High-Temperature Equilibrium Isotope Fractionation of Non-Traditional Stable Isotopes: Experiments, Theory, and Applications (Invited)
TL;DR: In this article, the fundamental driving forces for equilibrium inter-mineral fractionation comes from basic crystal chemistry and is invaluable for interpreting data from natural systems, which relies on refinements of equilibrium fractionation factors through a feedback between crystal chemical reasoning, ab initio predictions, experiments, and analyses of well-characterized natural samples.
Journal ArticleDOI
High-temperature Si isotope fractionation between iron metal and silicate
TL;DR: In this paper, the Si stable isotope fractionation between metal and silicate has been investigated experimentally at 1800, 2000, and 2200 C. The authors found that there is a significant silicon stable atomization fractionation at high temperature between metals and silicates in agreement with Shahar et al.
Journal ArticleDOI
Crystal chemical constraints on inter-mineral Fe isotope fractionation and implications for Fe isotope disequilibrium in San Carlos mantle xenoliths
TL;DR: In this article, a revised ionic model for predicting equilibrium iron isotope fractionation between mantle minerals and use it to interpret measured intermineral iron isotopic fractionation from five distinct mantle xenolith lithologies from San Carlos, Arizona.
