Abstract

Abstract In this study, we present results of luminescence dating using CW-OSL, LM-OSL and TL on heated quartz from the archaeological and historical site in Karakorum – the ancient capital of Mongolia, to test their convergence with the age control in the form of the Karakorum inscription 1346. The TL spectra conducted on quartz from red and grey coloured bricks appeared to be characteristic of the technological origin. Quartz TL from red bricks showed a UV emission band at ∼360 nm and a strong fast OSL component dominated signal. In contrast, blue emission detected in the TL spectra of grey coloured bricks, resulting possibly in the medium component dominated OSL signal. Finally, OSL and TL results gave dates from 1180±70 AD to 1360±70 consistent with the expected ages.

蒙古喀喇昆仑地区砖的CW-OSL、LM-OSL和TL定年:来自TL光谱的启示

摘要在这项研究中，我们介绍了使用CW-OSL、LM-OSL和TL对蒙古古都喀喇昆仑考古和历史遗址的加热石英进行发光测年的结果，以测试它们与喀喇昆仑1346铭文形式的年龄控制的一致性。在红色和灰色砖的石英上进行的TL光谱似乎是技术起源的特征。来自红砖的石英TL显示出约360 nm的紫外线发射带和强烈的快速OSL成分主导信号。相反，在灰色砖的TL光谱中检测到蓝色发射，可能导致介质成分主导的OSL信号。最后，OSL和TL结果给出了从公元1180±70到1360±70的日期，与预期年龄一致。

期刊介绍： Geochronometria is aimed at integrating scientists developing different methods of absolute chronology and using them in different fields of earth and other natural sciences and archaeology. The methods in use are e.g. radiocarbon, stable isotopes, isotopes of natural decay series, optically stimulated luminescence, thermoluminescence, EPR/ESR, dendrochronology, varve chronology. The journal publishes papers that are devoted to developing the dating methods as well as studies concentrating on their applications in geology, palaeoclimatology, palaeobiology, palaeohydrology, geocgraphy and archaeology etc.
