| Outline of Final Research Achievements |
In this study we focused on zircon crystal sampled from sand of major river, and conducted rock-magnetic and paleomagnetic experiment using single zircon crystal sampled from the sand. During a survey period we established the non-magnetic preparation method of zircon for paleomagnetic study and the rock-magnetic and paleomagnetic measurement technique for single zircon crystal. On the basis of experimental results we proposed the criteria to select suitable sample for paleointensity study, and we also demonstrated paleointensity experiment using the sample satisfying the criteria. We established a ground of paleomagnetic study using single zircon crystal, and the results from this study suggested that single zircon crystal would be applicable to paleointensity experiments.
