Paleomagnetic Study of Mesozoic Continental Sediments Along the Northern Tien Shan (China) and Heterogeneous Strain in Central Asia [PDF]
, 1991 A paleomagnetic study of rocks from the northern foot of the Tien Shan and the southern border of the Dzungar Basin, east of Urumqi (44.2°N, 86.0°E), spanning ages from middle Jurassic to early Tertiary was carried out to constrain the tectonic evolution

Historical evolution of the geomagnetic declination at the Royal Observatory of Madrid [PDF]
History of Geo- and Space SciencesThe agonic line, which represents geomagnetic declinations of 0°, recently crossed the Royal Observatory of Madrid (ROM) in December 2021, causing a shift in declination values from west to east.

Old magnetic declinations [PDF]
Terrestrial Magnetism, 1896 On account of the renewed interest being paid to old magnetic observations, I should like to inform you that I am continuing my researches, the results of which I published in my paper, “De Isogonen in de XVIde en XVIIde Eeuw, Utrecht, 1893.”The large number of old ship journals, in the government archives at The Hague, furnished me with a thousand new

Report on the magnetic survey in Slovakia for the 2014.5 epoch
Contributions to Geophysics and Geodesy, 2016 The models of the distribution of the elements of the geomagnetic field must be updated regularly. For this purpose geomagnetic measurements have to be carried out repeatedly at geomagnetic observatories as well as at temporary observation points.

Ultra-high energy cosmic rays: are they isotropic? [PDF]
, 2000 From the analysis of AGASA data above $4 \times 10^{19}$ eV, we show that the ultra-high energy cosmic rays flux is neither purely isotropic, nor reflects the expected anisotropy from a pure source distribution that maps large scale structure in the ...

Model magnetne deklinacije za Slovenijo ; The model of magnetic declination of Slovenia [PDF]
Geodetski Vestnik, 2012 Predstavljen je polinomski model magnetne deklinacije za območje Slovenije, ki zaradi svojega lokalnega značaja omogoča točnejše izračunavanje deklinacije, kot je to mogoče s svetovnimi modeli. Podlaga za izračun koeficientov modela so vrednosti magnetne
