van den Berg A.P.; Yuen D.A. (2002)The thermal conductivity of mantle materials decreases with higher temperatures and increases with greater pressure due to phonon mechanism, but increases with temperature for radiative transfer. This trade-off attribute ...
-
van Hunen J.; van den Berg A.P.; Vlaar N.J. (2001)Very low to zero shallow dip angles are observed at several moderately young subduction zones with an active trenchward moving overriding plate. We have investigated the effects of latent heat for this situation, where ...

Cadek O.; van den Berg A.P. (1998)In the framework of dynamical modelling of the geoid, we have estimated basic features of the radial profile of temperature in the mantle. The applied parameterization of the geotherm directly characterizes thermal boundary ...

van den Berg A.P.; Yuen D.A.; van Keken P.E. (1995)Numerical simulations of mantle convection with a composite temperature-dependent, Newtonian and non-Newtonian creep law have revealed a transition in the dominant creep mechanism with the increasing vigour of convection. ...

Cizkova H.; van Hunen J.; van den Berg A.P.; Vlaar N.J. (2002)Results of high resolution seismic tomography showing subducting slabs deflected in the transition zone and thickened in the lower mantle seem to call for slab material weaker than inferred from mineral physics deformation ...

van den Berg A.P.; Yuen D.A. (1997)The role of viscous heating in mantle flows has been studied within the framework of a steady-state, two-dimensional cartesian model with a composite non-Newtonian and Newtonian rheology. There is temperature-dependence ...
