| Research Abstract |
Preliminary study on tectonomagnetic evolution of serpentinites in southwestern Japan was carried out to verify the hypothesis of fossil serpentine diapirs indicated from a series of dipole magnetic anomalies。Structural and magnetic study in field to microscopic scale revealed two stage serpentinization accompanied by similar magnetic property within four areas. Shear deformation during second stage serpentinization implies extrusion of serpentinites.
