The Appalachian area as a tectonostratigraphic analogue for the Barents Sea shelf
Abstract The US Appalachian Basin and the Arctic Norwegian and Russian Barents Sea shelf (BSS) areas are two strategic provinces for the energy industry. The Appalachian Basin is a well‐studied, mature, onshore basin, whereas the offshore BSS is still considered a frontier area. This study suggests...

Abstract The US Appalachian Basin and the Arctic Norwegian and Russian Barents Sea shelf (BSS) areas are two strategic provinces for the energy industry. The Appalachian Basin is a well‐studied, mature, onshore basin, whereas the offshore BSS is still considered a frontier area.

Although the Appalachian and BSS areas reflect different times and settings, both areas began as passive margins that were subsequently subjected to subduction and continent collision associated with the closure of an adjacent ocean basin.
