Abstract:
The Curie temperature and thermomagnetic behavior of wholerock samples were measured in basalts recovered from Sites 442, 443, and 444 of DSDP Leg 58 in the Shikoku Basin, and from Site 446 in the Daito Basin, north Philippine Sea. Chemical composition and microscopic features of opaque oxides in the same samples were also investigated. Degree and mode of oxidation of titanomagnetite vary irrespective of site, lithology, or magnetic polarity, and no systematic correlation has been found between any two of these characteristics. Magnetic properties are systematically different between massive flows recovered at Hole 444A (Shikoku Basin) and Hole 446A (Daito Basin), although the controlling factor is unknown.
