| Abstract: | Results from a detailed magnetic survey and paleomagnetic measurements on oriented rock samples from the summit of Cobb Seamount indicate that the Seamount is complexly magnetized, recording at least one field reversal. The remanent magnetization probably resides in single-domain titanomagnetite (10 mole % ulvo¨spinel in solid solution with magnetite) which is unlike that found in dredged basalts. The simplest explanation for this difference is that the Seamount's pinnacle formed subaerially. |
