Research Abstract

We examined two different types of mantle-derived peridotites to clarify modification processes, especially to transportation of transitional-metal elements, by melts or slab-derived fluids : the one is xenoliths from sub-arc mantle beneath the volcanic front and the other is solid intrusive peridotite blocks and peridotites at the bottom of Oman ophiolite. Then, we identified that the sub-arc mantle beneath the volcanic front is highly metasomatized and some elements(e. g., Ni, Fe and platinum-group elements) are partly concentrated in there. In addition, we found H_2O-bearing inclusions in sub-arc mantle xenoliths. However there have been quite a few reports of H_2O inclusions even in arc-derived materials, we confirmed that H_2O is the main fluid phase within the sub-arc upper mantle beneath the volcanic front.
