Outline of Final Research Achievements |
Noble gases, halogens, calcium, potassium, barium, uranium in mantle peridotites from subduction zones and continental regions, exhumed metamorphic rocks derived from subducted slabs, and diamonds were simultaneously determined by using a combination of neutron-irradiation and high-sensitive noble gas mass spectrometry. The ubiquitous occurrence of sedimentary-pore-fluid-like subduction fluids associated with a small contribution of components of sediment or altered oceanic crust is best explained by a model where water with a pore-fluid signature is incorporated into subducting oceanic lithosphere as serpentine along fracture zones developed at the outer rise without significant modification in the halogen and noble gas compositions. The halogen and noble gas compositions of mantle peridotites from continental regions demonstrate that the influence of subduction driven metasomatism still remains beneath former subduction zones.
