THE STATE-OF-THE-ART OF DATING TECHNIQUES APPLIED TO ANCIENT MORTARS AND BINDERS: A REVIEW

摘要

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 (C-14) dating of complex mortars: can we assess the chances of successful dating?, (2) C-14 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.
