| Zusammenfassung |
| Foliated serpentinite with lattice preferred orientation (LPO) has strong elastic anisotropy,
and is considered as a cause for seismic anisotropy observed in subduction zones (Katayama
et al., 2009; Jung, 2011). However, deformation mechanisms of antigorite LPO are unclear.
We measured crystal orientation of antigorite and olivine, to clarify the chronological
relations between shear deformation and formation of antigorite LPO. The crystal
orientations are measured by the U-stage optically. In addition, we try to measure the
antigorite orientations by EBSD.
The studied samples are from lenticular serpentinite bodies intruded in a Jurassic
accretionary complex, Toba area, southwest Japan. Shear zones ( |
