Abstract
In olivine of upper mantle derivation, CO2 is the most commonly reported species of fluid1. Despite its great importance in the upper mantle2, H2O has rarely been reported (refs 3, 4 and E. Roedder, personal communication). Here we report that possible relics of H2O-rich fluid inclusions have been found in olivine of dunite from the alpine-type Iwanai-dake complex, northern Japan. These inclusions now consist mainly of serpentine and brucite, which may be the products of the reaction, olivine + H2O = serpentine + brucite, in a closed system. The abundance of such inclusions suggests that the Iwanai-dake complex may have been derived from the upper mantle in conditions in which some free H2O was available, such as the mantle wedge above a subduction zone.
