Outline of Final Research Achievements

I have carried out X-ray diffraction (XRD) analysis of fault rocks of the Itoigawa-Shizuoka Tectonic Line (ISTL) to estimate the age of fault movement of the ISTL. The XRD analysis shows that the existence of smectites becomes an index for the evaluation of fault activity. As a result of ESR dating of fault rocks of the ISTL, I confirm that ESR ages theoretically show the maximum age of the latest fault movement. The active zone of the ISTL is further extended to the 5km south of the present zone recognized as the ISTL Active Fault System. On the other hand, FMR signals, which is available in calculation of frictional heat energy necessary for the estimation of seismic magnitude, are not detected from the black fault rocks of the ISTL. The ESR spectral analysis of the Nojima fault rocks reveals that the source mineral of FMR signals is magnetite produced due to the disproportionation reaction progressing with thermal decomposition of siderite.
