This set of data files 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 data set 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. The data presented here are described and interpreted in a paper titled Biosiliceous, Organic-rich, and Phosphatic Facies of the Triassic in Northwest Alaska: Transect across a High-latitude, Low-angle Continental Margin.
