The dynamics and evolution of Venus' mantle are of first-order relevance for the origin and
modification of the tectonic and volcanic structures we observe on Venus today. Solid-state …

The shear modulus and attenuation of pure and therefore genuinely melt-free polycrystalline
aggregates of Fo90 olivine have recently been measured over a wide range of mean grain …

Modelling the geoid has been a widely used and successful approach in constraining flow
and viscosity in the Earth's mantle. However, details of the viscosity structure cannot be …

In many text books of fluid dynamics, and for most students, the word “fluid” refers to one of
the states of matter, either liquid or gaseous, in contrast to the solid state. This definition is …

In numerical simulations of mantle convection it is commonly assumed that the coefficients of
thermal expansion α and thermal conduction k are either constant or pressure-dependent …

Laboratory studies on deformation of olivine in response to applied stress suggest two
distinct deformation mechanisms in the earth's upper mantle: diffusion creep through …

The relation between gravity anomalies, topography and volcanism can yield important
insights about the internal dynamics of planets. From the power spectra of gravity and …

The elastic properties and the coefficient of thermal expansion (CTE) of the lithospheric
mantle are important parameters that affect the results of lithospheric modelling. However …

The numerical simulations of convection inside the mantle of the Earth or of terrestrial
planets have been based on approximate equations of fluid dynamics. A common …

During the last ice age cycles, large ice sheets have covered North America, Northern
Eurasia, Greenland and Antarctica. The Earth's crust and mantle has been depressed by the …
