 note = {P(論文), Dredged peridotite-pyroxenite samples from Antarctic Seamount B were examined to clarify the petrological signature. It is suggested from the tectonic setting that the emplacement of the peridotites was achieved by uplifting of upper mantle materials generated as a pre-oceanic rifting at the early stage of continental breakup between Antarctica and Australia. The Seamount B lherzolites contain a large volume of clinopyroxenes (6.5-12.9 modal%) and spinels (2.0-2.9 modal%). The Fo content in olivines ranges between 89.5 and 92.3. The spinels are highly aluminous (Cr#=7.8-15.7). Notably, the clinopyroxenes contain high Na_2O (1.24-2.35 wt%) and TiO_2 (0.27 to 0.85 wt%). The modal composition and mineral chemistry suggest that the Seamount B lherzolites display a 'fertile' subcontinental mantle signature ranging from the least to moderately depleted peridotite.},
