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).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1G5SSGC", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.684b0dacd4be020b699d9972.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_684b0dacd4be020b699d9972", "keyword": ["Alaska", "Atomic emission spectroscopy", "Brooks Range", "Carbon isotope analysis", "Earth science", "Energy Resources", "GeoScientificInformation", "Geochemistry", "Geochronology", "Geology", "Isotopic analysis", "Mass spectroscopy", "Mineral Resources", "North Slope", "Ocean/lake records", "Paleoclimate", "Radiometric dating", "Stratigraphic sequence", "Stratigraphy", "U-Pb geochronology", "USGS:684b0dacd4be020b699d9972", "Uranium-lead analysis", "Zircon"], "modified": "2025-07-09T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-146.31, 69.52, -145.70, 69.56", "theme": ["geospatial"], "title": "Zircon U-Pb, Organic Carbon Isotope, and Geochemistry Data from the Hue Shale and Canning Formation, Arctic Alaska, 2025"}
