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.

本地质年代学数据集包含来自碎屑锆石颗粒的铀-铅（U-Pb）同位素比值与放射测年年龄，作为投稿至《美国地质学会通报》（GSA Bulletin）的编号为B31749R1的稿件的补充数据，该稿件题为《早古生代张裂与被动陆缘张裂带再活化：来自渥太地堑波茨坦群碎屑锆石物源特征的启示》。本数据集的碎屑锆石采自寒武纪至奥陶纪的波茨坦群，样品采集地包括安大略省、纽约州与魁北克省。
