Time-dependence in 3D mantle convection models
The view of the lower mantle as a ?graveyard? of subducted crust prevailed for decades and was supported by the Hofmann and White (1982) ...

Thermal perturbations caused by large impacts and consequences ...Both are in a region with thin lithosphere, where a mantle plume has been suggested. Hence upper mantle viscosity could be regionally reduced, ... Plumes from the heterogeneous Earth's mantleThis large-scale flow is conceptually similar to a mechanism ad- vocated by King & Anderson (1995, 1998) for the generation of continental flood basalts.
