摘要

The north-central Appalachians occupy a critical posi- tion within the 3000+km-long Appalachian orogen, lying southwest of the boundary between the central and northern Appalachians (CNAB). The one-billion-year-long history of tectonic activity in the north- central Appalachians includes the assembly and breakup of a late Proterozoic supercontinent, the creation and evolution of the Appala- chains orogen during the Paleozoic, and the Mesoxoic transformation of the active orogen into a passive margin during Pangea's disassembly.
