Evidence for multiple recycling in Neoproterozoic through Pennsylvanian sedimentary rocks of the Central Appalachian Basin

Eriksson, Kjell; Campbell, Ian; Palin, J; Allen, Charlotte M; Bock, Barbara


The petrography of sandstones and neodymium (Nd) isotope compositions of mudstones from the central Appalachians indicate changing provenances during the late Neoproterozoic through Pennsylvanian evolution of eastern North America. In contrast, sandstones from all stratigraphic units are dominated by Grenvillian (950-1250 Ma) zircons. Neoproterozoic to Cambrian rift-related sandstones are mostly feldspathic arenites and contain detrital zircons that are exclusively Grenvillian. The associated...[Show more]
