| Abstract |
<p>Partition coefficients for rare earth elements (REEs) between apatite and basaltic melt were determined as a function of oxygen fugacity (<i>f<sub>O2</sub></i>; iron-wüstite to hematite-magnetite buffers) at 1 bar and between 1110 and 1175 °C. Apatite-melt partitioning data for R<sup>EE3+</sup> (La, Sm, Gd, Lu) show near constant values at all experimental conditions, while bulk Eu becomes more incompatible (with an increasing negative anomaly) with decreasing <i>f<sub>O2</sub></i>. Experiments define three apatite calibrations that can theoretically be used as redox sensors. </p>
