Improvement of luminescence and ESR dating and its application to Paleolithic sites in Far East Asia

(1)四通道（四个检测波长）TL/OSL装置的研制设计了一种四通道TL/OSL读出器，并对其性能进行了测试。用不同的波长对石英BLSL和长石IRSL的剂量依赖性进行了研究，用2 mg细粒、半细粒或粗粒样品进行波长检验，用最合适的波长进行测年。(2)四道TL/OSL装置和传统单道TL/OSL读数器的释光测年。日本：冲绳县的阿富拉贝壳丘和阿哈作物，长野县竹佐中原遗址、南索峰遗址等，来自三部（岛根县）的特弗拉斯和Asama（群马县）。海外：印度莫尔冈遗址和中国虎头梁、油坊、徐家窑遗址（泥河湾盆地）。(3)发表了几个发光测年的结果。日本：Umami-ninootani site（奈良Pref.），山道殿台遗址（宫城县）国外：朝鲜临津江、寒潭流域的旧石器时代遗址和地质样品，中国泥河湾盆地的旧石器时代遗址。(4)本研究项目的最后报告已发表。

(1) Development of a 4-channel (4 detection wavelengths) TL/OSL equipmentA 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.
