上海青龙镇遗址出土瓷器和砖瓦样品热释光特性研究
|
摘要
利用热释光测定年代技术对青龙镇出土样品的烧造年代进行检测分析,以求帮助了解不同历史时期青龙镇瓷器贸易的发展状况。为此,本工作以青龙镇遗址出土瓷器中的67件瓷片及4件砖瓦样品为研究对象,用热释光前剂量饱和指数法测定瓷片样品古剂量;用热释光高温细颗粒技术测定砖瓦样品古剂量;用厚源α粒子计数法和X射线荧光光谱技术测量样品年剂量。瓷片样品热释光年代结果从唐代至南宋不等,砖瓦样品年代结果为北宋时期烧造,与文献记载中隆平寺塔的始建时间相符。
Sixty three porcelain shards and four brick and tile samples unearthed from the Qinglong Town Archaeological Site in Shanghai were studied in this research. The thermoluminescence( TL) pre-dose technique was applied to acquire the paleo-dose of porcelain samples. The fine grain technique was applied to acquire the paleo-dose of brick and tile samples. The thick source α-counting method and X-ray fluorescence( XRF)spectrometry were used to acquire the annual dose of the samples. The TL dating results indicate that the porcelain samples were from the Tang Dynasty to the Southern Song Dynasty. The brick and tile samples dated back to the Northern Song Dynasty,which is consistent with what was recorded in the historical literature about the first construction years of the Longping Temple Pagoda.
