Research Abstract

This study showed relationships between olivine fabrics within peridotites and their tectonic background around the world. Antigorite is a metamorphic phase of olivine, high-temperature serpentine. We examined crystallographic fabrics of antigorite and its relation to olivine fabrics. Moreover, we measured seismic velocities of serpentinized peridotites in various degrees and calculated fabric-induced seismic properties of both olivine and serpentine in order to assess their effects on bulk seismic anisotropies. We also discussed the rheology and seismic properties of metamorphosed oceanic crust in the mantle wedge based on crystallographic fabrics of glaucophane and lawsonite.
