The State of Alaska funded this study, and funding for the analytical infrastructure of the Boise State University Isotope Geology Laboratory (BSUIGL) is provided by the National Science Foundation (grants EAR-0521221, EAR-0824974, EAR-1337887, and EAR-1735889 awarded to Mark D. Schmitz and others). We thank Dr. Schmitz for supporting the DGGS-BSUIGL collaboration; we also thank BSUIGL staff for their assistance. Discussions with Richard Lease and William Rouse provided additional stratigraphic context for the Canning River samples.
This dataset supports high-precision chronostratigraphic analysis of the rock units in Alaska's North Slope, contributing to improved geological understanding of the Colville foreland basin. By providing U-Pb zircon geochronology from bentonitic beds in deep-water shale sequences, the data enhances basin modeling, stratigraphic correlation, and age control critical to petroleum system evaluation. These results inform ongoing energy resource assessments and hydrocarbon exploration strategies as part of the Alaska Division of Geological & Geophysical Surveys' North Slope basin analysis and oil & gas research initiatives.
