Late Mesozoic - Early Cenozoic structural evolution of Sørvestsnaget Basin
Conclusion: This study focused on the structure and Late Cretaceous Early Cenozoic tectonic evolution of central part of the Sørvestsnaget Basin. Its location in the southwestern Barents Sea which is close to the Senja Fracture Zone makes this basin affected by the plate tectonic evolution. The evol...
