Abstract

After an intercomparison age experiment carried out in the framework of the first MODIS (MOrtar Dating Inter-comparison Study) project, the results showed general agreement both between optically stimulated luminescence (OSL) dating laboratories and with radiocarbon (14C) dating results. As the needs for the selection of samples convenient for an inter-comparison are not the same between 14C and OSL, for the second running, it has been decided to choose two different sample sets, one to share between the radiocarbon labs and one for the OSL dating ones. The results obtained by applying different experimental protocols (multigrain and single grain techniques) and different statistical models (weighted mean, central age mode, average dose model, minimum age model and exponential exposure dose) are discussed in this work.

光激发发光（OSL）灰泥年代相互比较研究。第二轮莫迪斯、灰泥定年相互比较研究

在第一个 MODIS（MOrtar Dating Inter-comparison Study）项目框架内进行的年代比对实验结果表明，光激发发光（OSL）年代测定实验室之间以及与放射性碳（14C）年代测定结果之间的比对结果基本一致。由于 14C 定年和 OSL 定年在选择便于相互比对的样品方面的要求不尽相同，因此在第二次比对中，决定选择两套不同的样品，一套供放射性碳实验室共享，另一套供 OSL 定年实验室使用。这项工作讨论了采用不同的实验方案（多颗粒和单颗粒技术）和不同的统计模型（加权平均值、中心年龄模式、平均剂量模型、最小年龄模型和指数暴露剂量）所得到的结果。

期刊介绍： Radiocarbon serves as the leading international journal for technical and interpretive articles, date lists, and advancements in 14C and other radioisotopes relevant to archaeological, geophysical, oceanographic, and related dating methods. Established in 1959, it has published numerous seminal works and hosts the triennial International Radiocarbon Conference proceedings. The journal also features occasional special issues. Submissions encompass regular articles such as research reports, technical descriptions, and date lists, along with comments, letters to the editor, book reviews, and laboratory lists.
