| Outline of Final Research Achievements |
In this study, we tried to analyse Os isotope ratios and Platinum group element abundance in abyssal peridotites from southwest Indian Ridge and Cayman trough. The Os isotope data suggest they are similar age distribution, but some peridotites from SWIR, which related with Gondwana, have older model ages than those from Cayman ridge. This result has presented in the international session of the JpGU.
