Apuupuu and Dana seamounts are located on the south flank of the island of Hawaii, near the active submarine volcano, Loihi. Though previous work suggests that they are older, inactive volcanoes, their ages and relationship to Hawaiian volcanism are uncertain. We make age estimates for these two seamounts by comparing paleomagnetic poles, derived using a magnetic inversion technique, to the Pacific apparent polar wander path. the paleopoles of Apuupuu and Dana seamounts are located at 65.8¿N, 9.2¿E and 66.7¿N, 358.7¿E, respectively. Both poles are insignificantly different and located on the Late Cretaceous part of the polar wander path, between the 82 and 72 Ma mean poles, suggesting that the seamounts formed contemporaneously long before their part of the Pacific plate drifted over the Hawaiian hot spot. ¿American Geophysical Union 1990 |
