A 3D computer model of the asthenosphere by Rice University geophysicists finds that the convective cycling and pressure-driven flow can sometimes cause the asthenosphere to move even faster than the tectonic plates riding atop it.

Cratonic lithosphere with a high-density root undergoes delamination when perturbed by mantle plumes from beneath. The removed cratonic root then thermally grows back, with its rock fabrics preserving recent mantle deformation.

Continental interiors may not be as tectonically stable as geologists think
