不同热释光法测定洛阳唐三彩年代结果比较

Comparison of the dating result of Luoyang Tang Sancai samples by different thermoluminescence techniques

采用前剂量法和细粒混合矿物技术法共测定了11件洛阳唐代、民国与现代三彩样品的年代,并对其结果进行了比较。用前剂量法测定11件洛阳三彩样品年代都得到了较好的结果,其中5件唐代洛阳三彩样品的测定年代都落在唐代年限范围内;5件烧制于1996年的仿唐代洛阳三彩样品的测定年代都在最近几十年范围内;一件民国仿唐代洛阳三彩样品的测定年代为距今114年。用细粒混合矿物技术法也测定了上述11件洛阳唐三彩样品的年代。其中5件洛阳唐代三彩样品中只有1件样品的测定年代结果落在唐代年限内;5件烧制于1996年的仿唐代洛阳三彩样品的测定年代都在最近二十年范围内,得到了较好的结果。一件民国仿唐代洛阳三彩样品的测定年代为距今882年,其结果显然是错误的。因此,选择合适的热释光方法测定洛阳唐三彩器物的年代非常重要。

The age of eleven Sancai samples of Luoyang Tang Dynasty,Republic of China and modern age has been determined by pre-dose method and fine-grain mineral mixture technique method.Their result has been compared. By using pre-dose technique,comparatively better result in dating the 11 Sancai samples were obtained.Among the 11 samples,the measured age of 5 Tang Dynasty samples fell into the age scope of Tang;the measured age of 5 modern imitation samples was several decades B.P.;the measured age of and imitation of Tang Sancai produced in Republic of China is 114 B.P.The above 11 Sancai samples of Luoyang Tang Dynasty were also measured by fine-grain mineral mixture technique.However,only the age of one sample among 5 Tang Dynasty samples fell into Tang Dynasty age scope;the measured age of 5 modern imitations fell into the scope of last twenty years, showing good result.The measured age of the imitation of Tang Dynasty Luoyang Sancai produced in 1996 fell into last several dozens of years scope;the age of the one produced during Republic of China was 882 B.P.,which is obviously wrong.Hence,choosing which appropriate thermoluminescence method to determine the age of Luoyang Tang Dynasty Sancai samples is extraordinary important.
