Late Cenozoic uplift and volcanism on Spitsbergen; caused by mantle convection?

A study examined the Svalbard uplift north of Scandinavia. One of several Cenozoic uplifts in the North Atlantic, the Svalbard may have been caused by boundary processes where hot-spot-influenced asthenosphere abuts cold, deep continental lithosphere.
