This data release contains concentration and isotope-dilution standard (IDS) recovery data from individual samples that are summarized and interpreted in the U.S. Geological Survey (USGS) Techniques and Methods (T&M) Report "Determination of Per- and Polyfluoroalkyl Substances in Water by Direct Injection of Matrix-Modified Centrifuge Supernatant and Liquid Chromatography-Tandem Mass...
Whole Rock Major and Trace Element Chemistry for Igneous, Metamorphic, and Mineralized Rocks Collected for Select Projects in Alaska Whole Rock Major and Trace Element Chemistry for Igneous, Metamorphic, and Mineralized Rocks Collected for Select Projects in Alaska
This dataset consists of one table containing whole-rock geochemistry data for 251 igneous, metamorphic, and mineralized (metasomatic) rocks from various locations across Alaska in support of mineral assessments of critical minerals and transboundary watersheds. The samples were collected mainly between 2019 and 2023, and all materials were analyzed by ALS Global, between 2019 and 2023...
Zircon U-Pb, Organic Carbon Isotope, and Geochemistry Data from the Hue Shale and Canning Formation, Arctic Alaska, 2025 Zircon U-Pb, Organic Carbon Isotope, and Geochemistry Data from the Hue Shale and Canning Formation, Arctic Alaska, 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...
