Data for Uranium-Lead Geochronology, Carbon and Sulfur Stable Isotopes, and Raman Spectroscopy from Graphite Creek, Alaska
This data release supports the paper titled, "Insights into the metamorphic history and origin of flake graphite mineralization at the Graphite Creek graphite deposit, Seward Peninsula, Alaska, USA", published in the journal Mineralium Deposita. 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 "sample_descriptions.csv". The raw numerical data are presented in tabular format. Additionally, plots of select zircon data - conventional discordia, U/Th vs age, U (ppm) vs age, and percent discordance vs age - are included in PDF format (zircon_plots.pdf), along with scanning electron microscope cathodoluminescence images of zircon in TIFF format. Folder "zircon_data" contains all zircon numerical data, plots, and images. Table "raman_peak_fits.csv" contains all raw Raman spectra peak fit data. Table "monazite_isotopic_data.csv" contains all monazite data. Table "carbon_sulfur_isotopic_data.csv" contains all carbon and sulfur data. Interpretations of the data are presented in the aforementioned journal paper.
