Abstract:
Seventeen samples from pillow or massive "zero age" fresh basalts from ODP Legs 106 and 109 were studied in order to examine their magnetic properties and oxidation degree. Thermomagnetic analyses of studied samples show Curie temperatures from 127°C to 220°C with reversible heating and cooling curves. Hysteresis parameters indicate the contribution of large Pseudo-Single Domain (PSD) grain of titanomagnetites with saturation magnetization between 0.4 and 0.7 emu/g which is almost twice that those of other recent mid-oceanic dredged basalts (e.g., FAMOUS and CYAMEX-RISE). The large grain sizes and higher magnetic mineral concentration may suggest a slower cooling of these basalts compared to those previously studied. Electron microprobe analyses of titanomagnetite grains combined with Curie point determinations give z = 0.3 for the degree of low temperature oxidation, which is close to the other values reported for low temperature oxidation of mid-oceanic ridge basalts.
