Detrital Zircon U-Pb and Hf isotope data from selected Appalachian rivers
This data release contains zircon U-Pb (n=1467) and Hf (n=332) data for five modern rivers (Connecticut, Susquehanna, Roanoke, Peedee, and Chattahoochee) draining the Appalachian mountain belt. The data show that zircon crystallization ages are characterized by several discrete populations that often correspond with orogenic episodes in the Mesoproterozoic and Paleozoic, with distinct differences between the various rivers sampled. ɛHf values are more consistent geographically, but differ between the Grenville and Paleozoic (Taconic, Acadian, and Alleghenian) orogenies.
