| Research Abstract |
(1) Development of a 4-channel (4 detection wavelengths) TL/OSL equipment
A 4-channel TL/OSL reader was newly designed and its property was examined. Dose dependences of quartz BLSL and feldspar IRSL were examined for different wavelengths.
Two mg of fine grain, semi-fine grain or coarse grain samples is used for wave-ength check, and the most proper wavelength is used for dating measurements.
(2) Luminescence dating by the 4-channel TL/OSL equipment and traditional 1-channel TL/OSL reader.
Japan: Afura shell mound and Aha crop in Okinawa Pref., Takesa-nakahara site, Minami-somine site etc. in Nagano pref., Tephras from Sambe (Shimane Pref.) and Asama (Gunma Pref.).
Oversea: Morgaon site in India and Hutouliang, Youfang and Xujiayao sites (the Nihewan Bain) in China.
(3) Several results on luminescence dating were published.
Japan: Umami-ninootani site (Nara Pref.), Yamadauenodai site (Miyagi Pref.) etc.
Oversea: Paleolithic sites and geological samples in Imjin and Hantan valley, Korea and Paleolithic sites in Nihewan basin, China.
(4) Final report of the present research project was published.
