The hiatus explains why the positive carbon isotope (δC13) excursion, typically associated with the Cenomanian/Turonian Boundary Event (CTBE), is absent at this locality.Keywords: Bouldin Creek, chronostratigraphy, sequence stratigraphyPermalink: https://doi.org/10.1190/image2022-3751498.1FiguresReferencesRelatedDetails Second International Meeting for Applied Geoscience & EnergyISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2022 Pages: 3694 publication data© 2022 Published in electronic format with permission by the Society of Exploration Geophysicists and the American Association of Petroleum GeologistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 15 Aug 2022 CITATION INFORMATION Arthur D.
