Abstract: | New palaeomagnetic analyses have been carried out in the Kerguelen Islands on 32 lava flows of well-established age (20–22 Ma). Combined with previous studies, they yield a reliable pole for the Lower Miocene for the Antarctic plate: N = 59 flows. 349.9°E, 83.5°S, A95= 6.1°. A reversal sequence reversed-normal has been identified in the Port Jeanne d'Arc section. |
