Palaeomagnetic Differences Between Normal and Reversed Field Sources, and the Problem of Far-sided and Right-handed Pole Positions

Analysis of palaeomagnetic data from the USSR, which Khramov and Sholpo have separated into normal and reversed mean data, reveals that there is considerable and obvious dissimilarity between normal and reversed regimes of the geomagnetic field source. These new data also strengthen the case for a world-wide eastward declination of the geomagnetic field during normal regimes, and westward (west of south) declination during reversed regimes. The question of how such fields could be maintained is discussed.
