Constraints from material properties on the dynamics and evolution of Earth's core
The Earth's magnetic field is powered by energy supplied by the slow cooling and freezing
of the liquid iron core. Efforts to determine the thermal and chemical history of the core have …

Modelling compressible mantle convection with large viscosity contrasts in a three-dimensional spherical shell using the yin-yang grid
PJ Tackley - Physics of the Earth and Planetary Interiors, 2008 - Elsevier
Here it is documented how an existing code for modelling mantle convection in a cartesian
domain, Stag3D, has been converted to model a 3D spherical shell by using the recently …

Tracking deep mantle reservoirs with ultra-low velocity zones
Some regions of the Earth's lowermost mantle exhibit anomalous seismic properties within a
thin zone, less than tens of kilometers in thickness, that directly overlies the core-mantle …

Longitudinal structure of Earth's magnetic field controlled by lower mantle heat flow
Thermal interactions between Earth's core and mantle provide the power that maintains the
geomagnetic field. However, the effect of these interactions and, in particular, the …

Regional stratification at the top of Earth's core due to core–mantle boundary heat flux variations
Earth's magnetic field is generated by turbulent motion in its fluid outer core. Although the
bulk of the outer core is vigorously convecting and well mixed, some seismic, geomagnetic …

Melting of the Earth's inner core
The Earth's magnetic field is generated by a dynamo in the liquid iron core, which convects
in response to cooling of the overlying rocky mantle. The core freezes from the innermost …

Generation of a strong magnetic field using uniform heat flux at the surface of the core
A Sakuraba, PH Roberts - Nature Geoscience, 2009 - nature.com
The Earth's main magnetic field is thought to be generated by motions in the planet's fluid
outer core, which lead to an effect similar to that of a dynamo,,. Recent high-resolution …
