Global Tin Isotope Compositions of Cassiterite for Ore System Analysis

A dataset of Sn isotope data includes 150 new analyses of cassiterite and four granite analyses. It constrains two major tin isotope fractionation steps related to magma separation and hydrothermal activity. The data demonstrate distinct Sn isotope differences across deposit types, host rocks, and deposit formation times.

Use Cases

• Model Rayleigh distillation for F ligand-induced Sn isotope fractionation using isotope composition data from orthomagmatic transitional environments.
• Analyze the relationship between mean δ124Sn values and deposit type, geological host rocks, and time of ore deposit formation to identify unified processes.
• Compare Sn isotope compositions in residual igneous rocks and pegmatite to trace the extraction of heavier isotopes during fluid separation.
• Track Sn isotope fractionation trends towards isotopically lighter compositions during hydrothermal system evolution using the provided isotope data.

Strengths

• Includes 150 new analyses of cassiterite, providing a substantial sample for isotope studies.
• Integrates four granite analyses for comparative context within magmatic-hydrothermal systems.
• Data is peer-reviewed and published in the journal Geosciences, ensuring scientific rigor.

Limitations

• The exact number of rows and column structure is unknown, limiting precise assessment of dataset scale and features.
• Sample data and file formats are unavailable, hindering immediate inspection and analysis workflow planning.
