Newtonian versus non-Newtonian upper mantle viscosity: Implications for subduction initiation

Abstract

[1] The effect of rheology on the evolution of the slab-tip during subduction initiation is analyzed using 2-D numerical flow models. Experimentally determined flow laws have both strong temperatureand stress-dependence, which leads to large local variations in viscosity with direct consequences for subduction initiation. We find that models with Newtonian… (More)
