Supplementary Tables for Sediment Melting Experiments

Seven tables present experimental data comparing sulfate-rich and graphite-rich sediments under high-pressure conditions. The dataset includes results from simulations indicating sediment melts have a negligible oxidizing effect on the mantle wedge. Authored by Shuo Xue and updated in March 2026, the data supports analysis of subduction zone geochemistry.

Use Cases

• Compare solidus temperature data between sulfate-rich and graphite-rich sediment types to model partial melting thresholds.
• Analyze experimental results at 1–3 GPa pressure to validate simulations of sediment behavior in subduction zones.
• Correlate sediment composition (sulfate vs. graphite) with predicted recycling pathways into arc magmas or the deep mantle.
• Use simulation outputs to assess the oxidizing effect of sediment melts on the mantle wedge.

Strengths

• Data is derived from controlled high-pressure experiments, providing empirical validation for geochemical models.
• The dataset explicitly compares two distinct sediment types (sulfate-rich and graphite-rich) under identical pressure conditions.
• Includes simulation results that extend experimental findings to subduction zone dynamics.
• Published under a permissive CC BY 4.0 license for reuse.

Limitations

• The dataset is small in scale (824.7 KB), limiting the volume of available experimental data points.
• Specific row counts, column structures, and sample data are unavailable, hindering immediate assessment of data granularity.
• Focus is on experimental and simulated conditions, not direct field measurements from specific geographic locations.
