Volcanic arc emplacement onto the southernmost Appalachian Laurentian shelf: Characteristics and constraints

  journal={Geological Society of America Bulletin},
In the southernmost Appalachians, the Hillabee Greenstone, an Ordovician volcanic arc fragment, lies directly atop the outermost Laurentian Devonian-earliest Mississip- pian(?) shelf sequence at the structural top of the greenschist facies Talladega belt, the frontal metamorphic allochthon along this orogenic segment. The Hillabee Greenstone was emplaced between latest Devonian and middle Mississippian time. It and the upper- most Laurentian section were later repeated together within a series…
