“…Viscosity of the overriding lithosphere, when present, is 2.9 × 10 4 Pa s and the viscosity of the mantle ranges between 30 and 40 Pa s. The obtained viscosity ratio between the slab and the upper mantle varies between 7.75×10 2 and 25×10 2 (Table 1), which is in the high range of proposed values (e.g. Billen et al, 2003;Faccenna et al, 2007;Funiciello et al, 2008;Wu et al, 2008;Loiselet et al, 2009Loiselet et al, , 2010. In the following, we directly express the quantities with their corresponding scaled values for a better relevance to real Earth.…”

“…Previous work has argued that the upper mantle is dominantly non-Newtonian and strain rate softening [Billen, 2008;Cizkova and Bina, 2013], which implies that the effective viscosity ratio between a slab and the ambient upper mantle should be relatively high. Nevertheless, the effective viscosity ratio that we use in our experiments (~160) is well within the previous estimates of approximately 50-500 [e.g., Schellart, 2008;Funiciello et al, 2008;Ribe, 2010;Wu et al, 2008;Loiselet et al, 2009;Li and Ribe, 2012]. For the density difference we consider a natural upper limit of Δρ = 80 kg m 3 , which would correspond to an old lithospheric slab in which all the oceanic crust has been altered to eclogite and with no heat diffusion into the slab.…”

“…We invariably observe (relatively fast) slab rollback in these models, whereas on Earth not all subduction zones show strong rollback and advancing trenches are also proposed (e.g. Funiciello et al, 2008;Schellart et al, 2008). OO3 and OO6 are in fact endmember models as on Earth the global coupling between plates may impose far-field control on the velocity of both overriding and subducting plate.…”
