Data for Uranium-Lead Geochronology, Carbon and Sulfur Stable Isotopes, and Raman Spectroscopy from Graphite Creek, Alaska
The data release includes zircon and titanite U-Pb-Thisotope and age data, monazite U-Pb-Th isotope, trace element and age data, carbon and sulfur stableisotope data, and graphite Raman spectroscopy data, from samples collected at the Graphite Creek deposit, Alaska. Sample location information and descriptions are in table "_sampleDescriptions_". Table "_ramanPeakFits_" contains all raw Raman spectra peak fit data. Table "_monaziteIsotopic_" contains all monazite data. Table "_carbonSulfurIsotopic_" contains all carbon and sulfur data. Folder "_zirconData_" contains all zircon numerical data, plots, and images. Raw numerical data are presented in tabular format; plots of select zircon data (conventional discordia, U/Th vs age, U (ppm) vs age, and percent discordance vs age) are presented in PDF format; scanning electron microscope cathodoluminescence images of zircon are presented in TIF format.
