  "description": "This dataset contains results from a stratigraphic section of the Hue Shale located along the Jago River in the Arctic National Wildlife Refuge at 69.9099, -143.3947 (WGS84). Sample heights were measured with a tape measure in a continuous succession. Zircon grains from volcanic ashes were analyzed via laser ablation at either the University of California, Santa Barbara (UCSB) or the University of Arizona Laserchron Center (ALC) using a Photon Machines Analyte 193-nm Excimer laser and Nu Instruments Plasma HR MC-ICPMS. Zircon grains from volcanic ashes were analyzed via chemical abrasion at the Berkeley Geochronology Center using a Sector 54 TIMS. 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°C with sodium peroxide and dissolved in dilute nitric acid via inductively coupled plasma-optical emission spectroscopy (ICP-OES) and inductively coupled plasma-mass spectroscopy (ICP-MS) by Agat Laboratories. Spectral Gamma Ray (SGR) measurements were collected in the field using a 90 second assay at 0.5 m intervals using a Radiation Solutions 230 Bismuth Germanate Oxide handheld instrument. The study was funded by the Energy Resources Program of the U.S. Geological Survey (USGS).",
