Beyond the thermal plume paradigm
[1] Geodynamic models of thermo-chemical plumes rising in a mantle wind suggest that we should abandon some paradigms based on the dynamics of purely thermal axisymmetric plumes. The head-tailExpand
A re-evaluation of metal diapir breakup and equilibration in terrestrial magma oceans
Abstract Due to mechanisms such as impact heating, early atmospheric thermal blanketing, and radioactive heating, the presence of at least one global magma ocean stage in the early histories ofExpand
N-body simulations of oligarchic growth of Mars: Implications for Hf–W chronology
Dauphas and Pourmand [2011. Hf–W–Th evidence for rapid growth of Mars and its status as a planetary embryo. Nature 473, 489–492] estimated the accretion timescale of Mars to be 1.8−1.0+0.9Myr fromExpand
Petrological constraints on the density of the Martian crust
New insights into the chemistry of the Martian crust have been made available since the derivation of crustal thickness maps from Mars Global Surveyor gravity and topography data that used aExpand
A community benchmark for viscoplastic thermal convection in a 2-D square box
Numerical simulations of thermal convection in the Earth’s mantle often employ a pseudoplastic rheology in order to mimic the plate-like behavior of the lithosphere. Yet the benchmark tests availableExpand
Thermochemical convection and helium concentrations in mantle plumes
Compositionally heterogeneous material may exist in the lowermost mantle [van der Hilst and Karason, Science 283 (1999) 1885–1888]. Here we use a numerical model to investigate the dynamics of (i)Expand
Oscillating and stagnating plumes in the Earth's lower mantle
Abstract We investigate the coupled effects of mineralogy and pressure on the dynamics of axisymmetric thermochemical plumes in the lower mantle, using both high resolution numerical experiments andExpand
The seismicity of Mars
The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission landed in Elysium Planitia on Mars on 26 November 2018 and fully deployed its seismometer by theExpand
Onset of solid‐state mantle convection and mixing during magma ocean solidification
Energy sources involved in the early stages of planetary formation can cause partial or even complete melting of the mantle of terrestrial bodies leading to the formation of magma oceans. UponExpand
The deep Earth may not be cooling down
Abstract The Earth is a thermal engine generating the fundamental processes of geomagnetic field, plate tectonics and volcanism. Large amounts of heat are permanently lost at the surface yielding theExpand
