| Outline of Final Research Achievements |
Paramagnetic defects and thermoluminescence colors were examined in order to show that those phsical properties are useful as proxies of the transport of the sediment on the surface of the earth. After establishing the techniques to quantify those properties, quartz grains were examined in atmospheric depositions in Japanese Islands and in present sediment of Kizu and Kurobe rivers. The oxygen vacancies in quartz of atmospheric depositions are correlated with the number of Kosa days in Fukuoka and in Yonago, but not in Akita. The oxygen vacancies and TL colors in quartz are found to be correlated with the basement rocks of the river reaches, which is reasonable as sediments are usually formed by the weathering of the basement rocks of the river reaches.
