[STT60-P08] Estimation of the mixing ratios of quartz in the possible source rocks that make up the present river bed sediments by using ESR
Keywords:ESR, Quartz, Provenance of sediments, Mixing ratios of sediments, Present river bed sediments
Recently, Electron Spin Resonance (ESR) signals are used as indicators of sediment provenance. The E1’ center signal intensity of quartz is shown to be a useful parameter to investigate the provenance of aeolian dust  - . The Al, Ti–Li, and E1' center signal intensities of quartz are useful in determining sediment provenance . The Al and Ti–Li center signal intensities of quartz are possible to estimate the mixing ratios of sediment provenance .
In this study, we will report estimation of the mixing ratios of the source materials that make up the present river bed sediments by using ESR signal intensities of Al, Ti-Li and E1’ centers.
