Detrital zircon geochronologic dataset of Late Mississippian to Middle Pennsylvanian sediment, southwestern Kansas and northwestern Arkansas

We report 1544 new concordant ages, 582 ages from Kansas core and 962 ages from Arkansas outcrop samples. U-Pb age spectra are characterized by major Grenville (900–1,300 Ma) and Taconic-Acadian (350–500 Ma) age clusters and minor components of older age groups, suggesting a persistent source in the Appalachians tied to the Alleghanian orogeny. However, by the Early Pennsylvanian, the Hugoton Embayment samples see the Appalachian source partially replaced by Yavapai-Mazatzal (1800–1600 Ma) and Granite-Rhyolite (1550–1300 Ma) grains, major components of the local basement, that suggest contributions from nearby ARM uplifts.
