Objective The main objective of this project is to investigate long-time evolution and structure of the fluid motion and magnetic fields produced by heat and mass transfers in the deep interiors of the Earth, planets and their moons. The project focuses on planets/moons with electrically conducting fluid interiors, where MHD dynamo could be active enough to create observable magnetic field. PROJECT PROPOSALS To investigate principal heat-mass-transfer, MHD regime and force balance in Ganymede moon of Jupiter, Uranus and Neptune. To estimate ancient Martian MHD dynamo action that is indicated by the recently observed strong magnetisation of some parts on the Martian crust. Using seismic measurements and linear heat-mass-transfer theory to find the Earth's inner rigid core age with the accuracy up to 30%. Basing on the Thellier method supplemented by microstructure and composition studies to obtain reliable 0.5-3 billions years old geomagnetic intensity data. Using single plagioclase crystals measurements for the dikes exposed in Karelia to estimate geomagnetic field intensity up 3 billion years ago. To investigate magnetic anisotropy of sedimentary rocks as possible source of up to a billion years old geomagnetic information. To investigate sufficient alternations of non-dipole or/and asymmetric to the rotation axis paleomagnetic field components. Modelling hit by very heavy meteorite and the inner rigid core growing start to investigate transition geodynamo states. Proposing magnetostratigraphic investigations of sedimentary and volcanic objects to test the geomagnetic reversal and dipole symmetries for the entire Proterozoic epoch. Looking for correlation between the magnetic intensity and reversal rate to sample paleomagnetic Cretaceous sections from Armenia and Georgia. Accumulating all the long-time data necessary for this project to create and maintain paleomagnetic and geo/planetary dynamo databases. To resolve higher hydro-magnetic anisotropy and developed MHD turbulence combining large-scale three-dimensional finite difference models with local shell models of MHD turbulence in planets/moons. Applying appropriate jump conditions to solve reduced simplified equations valid outside the MHD shear layers in order to produce new effective codes for 1D/2D/2.5D/3D geo/planetary/moon MHD dynamo models. Using new effective codes for parallel computers to extend planetary/moon dynamo models onto scales larger than a million years. Calculating the mean electromotive force for 3D MHD dynamo models of this project to understand the nature of their magnetic field generation and annihilation via the well-known alpha and beta effects of mean field models. To construct simplified, but realistic, 2D and 1D mean field MHD dynamo models that might be able to reproduce geomagnetic evolution on time scales up to a billion years.
