Inferences of mantle viscosity based on ice age data sets: Radial structure [PDF]
, 2016 We perform joint nonlinear inversions of glacial isostatic adjustment (GIA) data, including the following: postglacial decay times in Canada and Scandinavia, the Fennoscandian relaxation spectrum (FRS), late-Holocene differential sea level (DSL ...

On the impact of true polar wander on heat flux patterns at the core–mantle boundary [PDF]
Solid EarthThe heat flux across the core–mantle boundary (CMB) is a fundamental variable for Earth evolution and internal dynamics. Seismic tomography provides access to seismic heterogeneities in the lower mantle, which can be related to present-day thermal ...

The Ability of Significant Tidal Stress to Initiate Plate Tectonics [PDF]
, 2019 Plate tectonics is a geophysical process currently unique to Earth, has an important role in regulating the Earth's climate, and may be better understood by identifying rocky planets outside our solar system with tectonic activity.

Tomographic evidence for compositional heterogeneity deep in earth’s mantle [PDF]
, 2002 In the past decade, tomographic imaging has revealed that trajectories of mantle convection are more complex than expected from end-member models of unhindered whole mantle circulation or layered convection with an interface at 660 km depth.

Thermodynamic Limits on Magnetodynamos in Rocky Exoplanets
, 2010 To ascertain whether magnetic dynamos operate in rocky exoplanets more massive or hotter than the Earth, we developed a parametric model of a differentiated rocky planet and its thermal evolution.

Effects of adiabatic compression on thermal convection in super-Earths of various sizes
Earth, Planets and Space, 2018 We present two-dimensional numerical models of thermal convection of a compressible fluid in the mantles of super-Earths calculated under the truncated anelastic liquid approximation to discuss how adiabatic compression affects the thermal convection ...

, 2017 The energy balance of a partially molten rocky planet can be expressed as a non-linear diffusion equation using mixing length theory to quantify heat transport by both convection and mixing of the melt and solid phases.

Bifurcations and dynamics in convection with temperature-dependent viscosity in the presence of the O(2) symmetry [PDF]
, 2013 We focus the study of a convection problem in a 2D setup in the presence of the O(2) symmetry. The viscosity in the fluid depends on the temperature as it changes its value abruptly in an interval around a temperature of transition.

Overturn of ilmenite‐bearing cumulates in a rheologically weak lunar mantle [PDF]
, 2019 ©2019. American Geophysical UnionThe crystallization of the lunar magma ocean (LMO) determines the initial structure of the solid Moon. Near the end of the LMO crystallization, ilmenite‐bearing cumulates (IBC) form beneath the plagioclase crust.

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.
