| Outline of Final Research Achievements |
We carried out a research about construction of the systematic technique to understand indistinct fault displacement index of sediment quantitatively in an active fault outcrop. In black soil around the active fault, we confirmed that the measurement of magnetic susceptibility, anisotropy of magnetic susceptibility, paleomagnetism, water content and ignition loss, and analysis of volcanic ashes were effective. Based on a characteristic of each technique, we showed a systematic workflow to apply these techniques effectively. At first we sample the soil after having measured the magnetic susceptibility in an outcrop. Using the sample, we measure paleomagnetism, anisotropy of magnetic susceptibility, water content and ignition loss sequentially, and a workflow to analyze volcanic ashes and minerals into is effective. It is effective to add the carbon-14 dating.
