Data sharing of Trace element partitioning between apatite and silicate melts: Effects of major element composition, temperature, and oxygen fugacity, and implications for the volatile element budget of the lunar magma ocean

This repository contains all data used in Ji and Dygert (2024), along with two essential tools (Apatite_Kd_calculator.xlsx): 1. A calculator for apatite trace element partition coefficients 2. A Eu-in-apatite–plagioclase oxybarometer Update (2025-07-15 version): This version corrects a minor typo in the molecular weight of SiO₂ used in both tools. While the original error had a negligible effect on the calculated partition coefficients, this correction ensures full accuracy for future applications.
