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

(1) 4通道（4个探测波长）TL/OSL设备的研制新设计了一种4通道TL/OSL阅读器，并对其性能进行了测试。考察了石英和长石在不同波长下的剂量依赖性。2毫克细粒、半细粒或粗粒样品用于波长检查，最合适的波长用于测年。(2)采用4通道TL/OSL设备和传统的1通道TL/OSL阅读器进行发光测年。日本：冲绳县的Afura贝壳堆和Aha作物，长野县的竹-中原遗址，南-索米遗址等，三部（岛根县）和浅间（群马县）的Tephras。海外：印度摩根遗址和中国虎头梁、游坊、徐家窑遗址（泥河湾遗址）。(3)发表了若干发光测年结果。日本：鲜味-二野谷遗址（奈良县）、山道野代遗址（宫城县）等。海外：韩国临津、汉滩河谷旧石器时代遗址和地质样品，中国泥河湾盆地旧石器时代遗址。本研究项目的最终报告已经发表。

(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.
