Detailed U–Pb Zircon Data for Samples 85.1-21-DF05, DC23-91.7R-1, and 113.1-DF-14

This dataset presentsU–Pb isotopic data for zircon grains from three samples: 85.1-21-DF05, DC23-91.7R-1, and 113.1-DF-14. Each Excel worksheet corresponds to one sample and contains isotopic ratios, analytical uncertainties, and calculated ages for individual zircon grains. Table columns include: Grain name – Identifier for each zircon grain analyzed ⁽²⁰⁷⁾Pb/⁽²³⁵⁾U and ²⁰⁶Pb/²³⁸U ratios – Measured isotopic ratios and associated 1σ uncertainties (in %) RHO – Correlation coefficient between ²⁰⁷Pb/²³⁵U and ²⁰⁶Pb/²³⁸U ²⁰⁷Pb/²⁰⁶Pb ratio – With 1σ uncertainty (%) ⁽²⁰⁷⁾Pb/⁽²⁰⁶⁾Pb, ²⁰⁶Pb/²³⁸U, and ²⁰⁷Pb/²³⁵U ages – Calculated ages with 2σ absolute uncertainties (in Ma) Concordia age – Concordia-intercept age with 2σ absolute uncertainty, where applicable All analyses were conducted using LA-ICP-MS, and ages are uncorrected for common Pb unless otherwise noted.
