Archaeomagnetic investigations of geomagnetic secular variations
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1982Abstract Bulgarian archaeomagnetic directions and intensities show a satisfactory agreement with those for Ukraine and Paris. Bauer plots of declination against inclination show both clockwise and anticlockwise looping through the last eight millennia. The necessity for accurate dating of samples studied is stressed.

Study of Geomagnetic Secular Variation in China
Chinese Journal of Geophysics, 2010AbstractUsing the data of the geomagnetic diurnal averages during 2000~2004 at 34 observatories in China, we calculated the mean annual change rates on the quiet days and all days, and the fitting annual change rates on the quiet days. The Taylor polynomial model and the spline model of the geomagnetic secular variation in China for epoch 2000.0~2005.0
