Zhaojinci Granitic Rock Geochemistry and Zircon Data for Mineral Potential Assessment

Geochemical and isotopic data for twelve granitic stocks from the Zhaojinci district in southern Hunan, South China. The dataset includes zircon U-Pb dating, trace element analysis, and Hf isotope results used to determine formation ages and magmatic sources. It was authored by Feiyun Xiao and published on figshare under a CC-BY-4.0 license.

Use Cases

• Determining rock formation ages based on zircon U-Pb geochronology results.
• Assessing magmatic source and crustal components based on zircon εHf(t) values and TDM2 ages.
• Evaluating ore-bearing potential for Cu skarn mineralization based on Ce4+/Ce3+ ratios, temperature, and Dy/Yb ratios.
• Correlating local magmatism with regional Jurassic metallogenic events in southern Hunan.

Strengths

• Data includes specific geochemical signatures such as average Ce4+/Ce3+ ratios of 99 and temperatures averaging 784 °C.
• Zircon U-Pb dating provides precise formation ages between 168–159 Ma.
• Published under a permissive CC-BY-4.0 license for reuse.

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 small (210.2 KB), indicating limited scope.
