Tholeiitic pillow basalt dredged from the Hakuho seamount located in the Kinan seamount chain, the Shikoku Basin, has peculiar magnetic properties; wide range intensity and high stability of natural remanent magnetization (NRM), low susceptibility, high initial Curie temperature and relatively small lattice constant. Four specimens of the pillow basalt have been cored from rim to center of one boulder sample. The NRM intensity decreases from center to rim, but the stability increases from center to rim. Reduced intensity of NRM in the rim is possibly caused by a high degree of low temperature oxidation. High magnetic stability is due to the very fine size of ferromagnetic minerals.
