Sulfur-Enriched Sub-Arc Fluids Driving Deep Sulfur Cycling in Subduction Zones

Five tables present results from a geochemical study of subduction zone processes. The dataset includes reconstructed bulk chemical compositions of slab-derived fluids, major-element contents in host minerals, and thermodynamic modelling parameters. It was authored by Dongbo Tan and last updated on June 4, 2026.

Use Cases

• Reconstructing slab-derived fluid compositions based on multiphase fluid inclusion data.
• Modeling rock devolatilization processes based on variations in bulk-rock H2O, carbon, and sulfur concentrations.
• Calibrating thermodynamic models using provided solution model parameters.
• Analyzing major-element heterogeneity in host omphacite minerals surrounding fluid inclusions.

Strengths

• Dataset is structured into five distinct tables for specific analytical and modelling results.
• Data is openly shared under a CC-BY-4.0 license, permitting reuse with attribution.
• Includes both observational data (Raman modelling, chemical compositions) and model parameters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 87.0 KB, indicating limited scope.
