This data release contains 60 detrital zircon age spectra, based on U and Pb isotope ratio measurements for 9399 single grains. The samples are from Paleogene strata of the U.S. Gulf Coast. Of the 9399 single grain measurements, we recommend that 8640 yield ages that are suitable for construction of detrital zircon age spectra. Comments tagged to individual grains explain the reasoning for exclusion of a single grain measurement from age spectra, mostly including high discordance and/or uncertainty. The samples were collected along the strike of the U.S. Gulf Coast basin between western Alabama (the eastern U.S. Gulf Coast) and the Rio Grande river (the southwestern boundary of the U.S. Gulf Coast). The highest...

This dataset accompanies planned publication titled "The Far-Field imprint of the LPIA, its demise, and the onset of a dust-house climate across the Eastern Shelf of the Permian Basin". Zircon ages presented in this dataset are from rocks collected across the eastern margin of the Permian Basin, Texas. The U-Pb zircon ages are used to investigate changes in provenance in this region as a result of a changing hydroclimate and tectonics. Samples were collected from this region by Neil Griffis and Neil Tabor between March 2019 and April 2021. The data were collected at the University of California, Davis and the University of Texas, Austin between April 2019 and August 2021.
