Zircon U-Pb, Organic Carbon Isotope, and Geochemistry Data from the Hue Shale and Canning Formation, Arctic Alaska, 2025

Metadata Updated: September 12, 2025

This dataset contains results from three stratigraphic sections of the Hue Shale located in and adjacent to the Arctic National Wildlife Refuge in northeastern Alaska. Sample heights were measured with a tape measure in continuous successions. Zircon grains from volcanic ashes were analyzed via laser ablation at the University of California, Santa Barbara (UCSB) using a Photon Machines Analyte 193-nm Excimer laser and Nu Instruments Plasma HR MC-ICPMS. Bulk mudstone samples were subject to a variety of analyses. Total organic carbon (TOC) and total carbon (TC) were analyzed using a LECO Carbon Analyzer Model C744, programmed pyrolysis was performed using a HAWK instrument, and organic carbon isotopes of TOC were measured via isotope ratio mass spectrometry using a Thermo-Scientific MAT 253, all run at the USGS Petroleum Geochemistry Research Laboratory. Elemental abundances were determined on samples fused at 750 degrees C with sodium peroxide and dissolved in dilute nitric acid via inductively coupled plasma-optical emission spectroscopy (ICP-OES) and ICP-MS by Agat Laboratories. The study was funded by the Energy Resources Program of the U.S. Geological Survey (USGS).
