| Outline of Final Research Achievements |
The Raman spectra of carbonaceous material in natural and experimental pseudotachylytes and fault gouges were analyzed to detect increased heating on faults. The results indicate that the Raman spectra can successfully detect increased carbonization associated with frictional heating. This increased carbonization can occur in ~4-16 s and is preserved even after alteration of fault materials. The comparison between experiment and Raman data demonstrated that there is a correlation between the average shear stress and the Raman spectra. Using the correlation, the average coseismic shear stress was estimated. Raman analysis of carbonaceous material-bearing faults will be useful for estimation of coseismic fault strength.
