Virtual dipole moment variations through the Proterozoic-Phanerozoic eons

The international bank of virtual dipole moment (VDM) data, combined with materials from recent publications (3384 values in total), served as a basis for the analysis of the VDM’s distribution through the Proterozoic and Phanerozoic eons (0–2.6 Ga). The VDM distribution obtained by the method of a moving average exhibits a positive linear trend from 3.7 × 10 22 Am 2 2.6 Ga ago to 5.8 × 10 22 Am 2 at present. Against the background of this linear growth, fluctuations with a periodicity of approximately 390 Ma are defined. The obtained data substantially specify the available data on the behavior of the magnetic field during the Proterozoic and Phanerozoic eons and should be taken into consideration for modeling the physical processes in the development of the Earth in the geological past and predicting its ecological and energetic evolution in the future.
