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. For a full explanation of methods and analytical results, see the companion manuscript Botterell et al. (2025).
