Fig. 3From: Tectonic plates in 3D mantle convection model with stress-history-dependent rheologyThe time evolution of the surface plate motions. Snapshots of the distributions of viscosity \(\eta\) (colour) and velocity \({\varvec{V}}\) (arrows) in a horizontal plane along the surface at the elapsed times indicated in the figure. The values of \(\eta\) are normalised by \(\eta _p\), the viscosity of intact material at the surfaceBack to article page
