The most recent workshop on mortar dating (25–27 Oct. 2018, Bordeaux, Montaigne University, France), which closely followed the publication of an extensive round robin-exercise involving several laboratories, was an opportunity to review the history and challenges of mortar dating methods and procedures currently in use. This review stems from the keynote lectures presented at the meeting, and wishes to summarize recent results, present trends, and future challenges. Three major areas are brought into focus (1) radiocarbon (14C) dating of complex mortars: can we assess the chances of successful dating?, (2) 14C dating of archaeological carbonate materials: difficulties, new directions and applications, and (3) single grain optically stimulated luminescence (OSL) dating of mortars in architectural archaeology: the current state of the art. This paper reflects the material presented by the authors and discussed at the workshop.

应用于古代迫击炮和粘合剂的最先进的约会技术：回顾

最近一次关于砂浆测年的研讨会（2018 年 10 月 25 日至 27 日，波尔多，法国蒙田大学）紧随出版了涉及多个实验室的广泛循环练习，是回顾砂浆历史和挑战的机会目前使用的约会方法和程序。这篇评论源于会议上的主题演讲，并希望总结最近的结果、当前的趋势和未来的挑战。重点关注三个主要领域 (1) 放射性碳 (14C）复杂迫击炮的约会：我们可以评估成功约会的机会吗？，（2）14考古碳酸盐材料的 C 年代测定：困难、新方向和应用，以及 (3) 建筑考古中砂浆的单颗粒光激发发光 (OSL) 年代测定：目前的技术水平。本文反映了作者提出并在研讨会上讨论的材料。
