Late Paleozoic granitic rocks have been identified in two drill holes south of the proposed Alleghanian suture separating the Suwannee terrane from terranes to the north. These granites are the only known expression of magmatism on the accreted Gondwanan plate during the Alleghanian collision of Laurentia and Gondwana, an event that represents the final episode in the assembly of Pangea. Zircons from samples of granite from drill holes in southwestern Georgia and northern Florida were analyzed by ion probe, yielding igneous crystallization ages of 294 ± 6 and 296 ± 4 Ma (2σ), respectively. Xenocrystic zircons with ages of ca....
