Dynamic effects of a step-wise increase in thermal conductivity and viscosity in the lowermost mantle
[1] We present numerical models of mantle convection incorporating changes in viscosity and thermal conductivity at depth. Increasing the viscosity and/or thermal conductivity by a factor of 5 at depths below 2000 km increases the size and stability of thermal upwellings. Decreasing the thermal conductivity beneath 2000 km, in contrast, has comparatively little effect on thermal upwellings. Inc...
متن کاملVariable azimuthal anisotropy in Earth's lowermost mantle.
A persistent reversal in the expected polarity of the initiation of vertically polarized shear waves that graze the D'' layer (the layer at the boundary between the outer core and the lower mantle of Earth) in some regions starts at the arrival time of horizontally polarized shear waves. Full waveform modeling of the split shear waves for paths beneath the Caribbean requires azimuthal anisotrop...
متن کاملGlobal P wave tomography of Earth’s lowermost mantle from partition modeling
[1] Determining the scale-length, magnitude, and distribution of heterogeneity in the lowermost mantle is crucial to understanding whole mantle dynamics, and yet it remains a much debated and ongoing challenge in geophysics. Common shortcomings of current seismically derived lowermost mantle models are incomplete raypath coverage, arbitrary model parameterization, inaccurate uncertainty estimat...
متن کاملElasticity of Mg2SiO4 ringwoodite at mantle conditions
The themoelastic properties of Mg2SiO4 ringwoodite at mantle pressure and temperature conditions are reported based on ab nitio molecular dynamic simulations. A third-order Birch–Murnaghan equation at a reference temperature of 2000 K is defined by 0 = 138 GPa, K′ 0 = 5.2, and V0(2000 K) = 560.3 Å3. The Grűneisen parameter is determined to be γ(V) = γ0(V/V0(298 K))q with 3 δT 0 = 1.22 and q= 1....
متن کاملTemperature profile in the lowermost mantle from seismological and mineral physics joint modeling.
The internal structure of the core-mantle boundary (CMB) region of the Earth plays a crucial role in controlling the dynamics and evolution of our planet. We have developed a comprehensive model based on the radial variations of shear velocity in the D'' layer (the base of the lower mantle) and the high-P,T elastic properties of major candidate minerals, including the effects of post-perovskite...
