    • Geochemical, Geochronologic, Rock-Eval, and Spectral Gamma Ray Data for Selected Triassic Rocks in Northwestern Alaska

    Metadata Updated: January 7, 2026

    This dataset contains analyses of samples representing the Triassic Shublik and Otuk Formations in Alaska. The samples were collected from the Brontosaurus 1 well and measured stratigraphic sections at Surprise Creek and Cape Lisburne. The dataset includes total organic carbon (TOC), Rock-Eval (Tmax) data, geochemical data from inductively coupled plasma-optical emission spectroscopy-mass spectroscopy (ICP-OES-MS) and X-ray diffraction (XRD), U-Pb zircon ages, and spectral gamma ray profiles.
