The effect of temperature dependent viscosity on the structure of new plumes in the mantle : Results of a finite element model in a spherical , axisymmetric shell

Abstract

We have developed a finite element model of convection in a spherical, axisymmetric shell that we use to simulate upwelling thermal plumes in the mantle. The finite element method provides the flexibility to include realistic properties such as temperature-dependent viscosity, the focus of this paper. We used this model to investigate the effect of… (More)
