Total organic carbon, programmed temperature pyrolysis, vitrinite reflectance, organic carbon isotopes, elemental, and spectral gamma-ray data from the Cretaceous Hue Shale (Jago River outcrop), Arctic Alaska, USA

Chemostratigraphic signatures were recorded in a 113 m thick outcrop of late Albian to early Campanian (~103–82 Ma) Hue Shale exposed on the bank of the Jago River in the coastal plain (“1002 Area”) of the Arctic National Wildlife Refuge (ANWR), Alaska. Spectral gamma-ray (SGR) data was collected in situ across the Jago River section. A total of 250 samples consisting of predominantly clay-rich mudstone were collected for organic and inorganic geochemical analyses. This data release includes SGR, total organic carbon, programmed temperature pyrolysis, vitrinite reflectance, organic carbon isotopes, and elemental abundance results.
