Two very important mechanisms that have been considered in numerical studies of mantle dynamics are the role of the endothermic phase transition at 670 km depth, and the decompression plume melting. The 670 km depth phase transition opposes the flow of material across it, favouring a tendency towards layered convection in the …

Spletmoist convection: bubble and plume. The present paper re-views the investigations of this period, and suggests how the mass-ﬂux convection parameterization formulation emerged from these early investigations. The choice of the steady-plume model as a key ingredient of the mass-ﬂux formula-tion is especially carefully discussed.

Splet01. dec. 2015 · It was found that local pressure gradient is proportional to the degree of mixing of ambient air into the plume.

Edge-driven convection is an asthenospheric small-scale convective instability caused by a gradient of the lithospheric thickness (i.e., lithospheric step) (e.g., King & Anderson, 1998). In this case, we assume that the lithosphere under the LT zone ...
