Research Abstract

In order to constrain degassing history of the Earth’s mantle, I conducted studies on melt inclusions within Cr-spinel from 2.7 Ga and 3.5 Ga komatiite. However, those melt inclusions are not large enough to analyze with the secondary ion micro spectrometry (SIMS-1280) at Woods Hole Oceanographic Institution. I will analyze them with newly installed Nano-SIMS at JAMSTEC. Three peer review papers which are related to this study are published.
