Calcite U-Pb and Sr Isotope Data for Hydrothermal Gold System

Supplementary material for a study on a long-lived hydrothermal gold system, authored by Xiheng He. It includes analytical results from laser ablation and solution-based mass spectrometry techniques. The dataset was last updated in April 2026.

Use Cases

• Determining the timing of hydrothermal events using U-Pb isotope ratios from calcite samples (Table S1).
• Tracing fluid sources and rock interactions by analyzing strontium (Sr) isotope ratios in calcite, limestone, and spilite (Tables S2, S3).
• Correlating multiple geochronological and isotopic datasets to model the evolution of a multistage gold system.

Strengths

• Provides in situ U-Pb dating results for calcite, a method critical for direct dating of mineralization.
• Includes Sr isotope data from three distinct sample types (calcite, limestone, spilite) for source tracing.
• Published under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.

Limitations

• Small dataset size of 5.9 MB, indicating a limited number of sample analyses.
• Sample count and specific row numbers for tables are not provided in the description.
• Contains supplementary material; the primary research context is required for full interpretation.
