Data for "Mineral/melt partitioning of the first-row transition elements, Ga, and Ge during lower-crustal crystallization: Controls on deep metal fractionation in hydrous arcs"

This record contains the supplementary datasets, a partition coefficient (D) calculator, and supporting documentation associated with this study.

Supplementary Data (Excel workbook)

Supplementary Data S1–S10 are provided in a single Excel workbook and include:

Sheet S1: Fourier Transform Infrared (FTIR) spectroscopy analytical results

Sheet S2: Filtered experimental dataset

Sheet S3: Reference list of filtered dataset

Sheet S4: Recalculated mineral–melt partition coefficients (molar basis)

Sheet S5: Pearson correlation coefficients and associated p-values

Sheet S6: Fitting equation parameters

Sheet S7: Dataset plotted on the TAS diagram

Sheet S8: Modeled liquid and mineral composition at 0.75 and 1.5 GPa (Continuous fractional crystallization)

Sheet S9: Modeled liquid and mineral composition at 0.75 and 1.5 GPa (Episodic fractional crystallization)

Sheet S10: Bulk and mineral-specific partition coefficients (D values) for both continuous and episodic fractional crystallization scenarios.

Supplementary partition coefficient (D) calculator (Excel file)A separate Excel file is provided as a D-value calculator, which implements the parameterization developed in this study. This tool allows users to compute mineral–melt partition coefficients as a function of pressure, temperature, oxygen fugacity, and mineral and melt composition.

Supplementary Document (Word)A supplementary document is also provided, containing detailed descriptions of data compilation, filtering criteria, and standardized data processing (Text S1), as well as the fractional crystallization model (Text S2). It additionally includes supplementary tables (Table S1–S2) and all supplementary figures (Figs. S1–S31).
