“…База в последние годы была обновлена [12][13][14]24, 25] и для интервала 0-4.2 млрд лет составляет несколько тысяч значений ВДМ по более чем 320 литературным источникам. Эта интернациональная база данных, дополненная нами результатами исследований [9,20,28,29], послужила основой этой работы. Используемая в работе обновленная база на середину 2018 г. включает в себя 5645 значений ВДМ и соответствующие им определения абсолютного возраста.…”

The data of the International Bank of Digital Information on the time distribution of the virtual dipole moment (VDM), supplemented by the data of more recent studies (a total of 5645 values) were used as the basis of the virtual dipole moment values distribution analysis for the Earth history within the concept of the Earth's magnetic dipole field. The results revealed the positive linear trend from 4.21022 4.2 billion of years ago up to Am2 to 5.151022 Am2 at resent time. Unevenly distrib-uted VDM fluctuations varying in time from 1.7 to 3.71022 Am2 with a wavelength varying from 220 to 920 million years and with the average periodicity near 570 Ma were estimated on the back-ground of linear increase of the field. By the order of magnitude this corresponds to the duration of the geological Wilson cycle. For the first time it is revealed that the magnetic field magnitude oscil-lations in time have an oscillating character with decay towards the present.

“…Precambrian (>540 Ma). In an attempt to identify the better results and to provide objective grounds for rejecting poorer data, Biggin and Paterson (2014) (Donadini et al 2011), the Lake Shore Traps (Kulakov et al 2013), the Gardar lavas (Thomas and Piper, 1995), the Sudbury irruptive (Schwarz and Symons, 1970), the Matachewan dykes (Macouin et al 2003;Smirnov and Tarduno, 2005;Halls et al 2004), the Burakovka intrusion (Smirnov et al 2003)…”

“…Some studies suggest (e.g., Kosterov et al, 2009;Engelmann et al, 2010) that LTD may also have a similar effect for low-Ti titanomagnetites (up to 55% Ti content) due to the presence of an isotropic point (Syono, 1965;Kakol et al, 1991). Thellier experiments combined with LTD (the LTD-Thellier method) have resulted in a higher success rate and better quality of paleointensity results from extrusive and intrusive rocks (Schmidt, 1993;Celino et al, 2007;Kulakov et al, 2013).…”

“…In order to reduce the effect of magnetic remanence carried by large PSD and MD grains, samples were subjected to three lowtemperature demagnetizations (LTD) in liquid nitrogen after the measurement of NRM and after each heating (e.g., Kobayashi and Fuller, 1968;Celino et al, 2007;Kulakov et al, 2013). The magnetic remanence was measured after LTD treatment and, for the Binneringie Dyke samples, also before LTD. After the experiment, the measured data were plotted on an Arai (NRM-remaining versus pTRM-gained) plot (Arai, 1963; (Figs.…”
