Detrital zircon U-Pb geochronology data from the Potsdam Group

This geochronology dataset contains U-Pb isotopic ratios and radiometric ages from detrital zircon grains that complement GSA Bulletin submission, B31749R1, entitled \"Early Paleozoic rifting and reactivation of a passive-margin rift: insights from detrital zircon provenance signatures of the Potsdam Group, Ottawa graben\". The detrital zircons are from the Cambrian to Ordovician Potsdam Group, and samples were obtained in from Ontario, New York State, and Quebec.
