Polarity excursion
| Словарь стратиграфических терминов |
A. a magnetostratigraphic polarity unit that may not be clearly classifiable as normal or reversed but may be designated as intermediate in direction. b. a swing in the direction o f the earth`s dipole magnetic field, with typical amplitude of 15 degrees and period of 102 to 104 years (harland et a l, 1982, p. 63; 1990, p. 140-141).
