Convection–driven geodynamo models [PDF]
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2000 Summary: There has been significant progress in the development of numerical geodynamo models over the last five years. Advances in computer technology have made it possible to perform three-dimensional simulations, with thermal or compositional convection as the driving mechanism.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract The Ediacaran–Cambrian (∼635–539 Ma) geomagnetic field is characterized by unusually high reversal rates and markedly weakened field strength. Estimates of these reversal frequencies can reveal key aspects of deep Earth dynamics and their potential influence on surface environments and early complex life.

Current state of Computational Geodynamo
, 2016 This project describes the physical and mathematical framework for simulating Earth's dynamo using Magneto-Hydrodynamics. Description of the technique can be found in review papers on geodynamo by Gltazmaier and Roberts and Kono.

Geophysical Research LettersThe precipitation of magnesium oxide (MgO) from the Earth's core has been proposed as a potential energy source to power the geodynamo prior to the inner core solidification. Yet, the stable phase and exact amount of MgO exsolution remain elusive.

Stochastic model of 6-jet kinematic dynamo [PDF]
E3S Web of Conferences, 2019 The low-moded stochastic model of kinematic geodynamo is studied. The model is based on the indirect data about the large-scale structure of convection.

Testing the Accuracy of Paleointensity Estimates Using Experimental Pottery Assemblages
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Paleointensity estimates from archaeological pottery represent a key source of information on Holocene variations in geomagnetic field intensity. Yet, pottery rarely exhibits ideal single‐domain behavior that fully satisfies the theoretical assumptions underlying absolute paleointensity methods.

Kinematic-gravity model of geodynamo
Геофизический журнал, 2013 Based on the results of solving the inverse problem of magnetometry and analysis of some known models of the Earth magnetic field generation a model is proposed in which the current producing magnetic field is the vortex motion of positively charged ...

Magnetohydrodynamics, 2012 We consider how information on geostrophic flows in the planetary cores, taken from 3D simulations in the sphere, can be used in 2D Parker's geodynamo model with the simple forms of the $α$-quenching. Using cluster computer systems dependence of dynamo equations solution on the magnitudes of $α$- and $ω$-effects is studied.

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract The cores of rocky planets, including the Earth, are believed to contain light elements such as silicon, oxygen, sulfur, hydrogen, and carbon. Amongst them, sulfur appears to be rich in the cores of small terrestrial bodies like Mars and Ganymede. To understand the evolution of sulfur‐rich cores in the presence of other light elements, we have
