25-27 Oct 2018 Bordeaux (France)



MoDIM 2018 continues a 10-year-old tradition of international meetings dedicated to radiocarbon and luminescence dating of archaeological lime mortars and anthropogenic carbonates in general. Previous Mortar Dating Workshops were held in Finland (2010), Spain (2012), Italy (2014), Switzerland (2015), and during specific sessions at several International Radiocarbon Conferences and International "Radiocarbon & Archaeology" Symposia.

The underlying theme of MoDIM 2018 is the characterization of archaeological lime mortar and lime plaster prior to radiocarbon and luminescence dating. More specifically, the focus of the meeting will be on methodologies aimed at identifying, isolating and removing potential sources of contamination for radiocarbon dating and at overcoming problems of residual geologic signals in insufficiently light-exposed materials for luminescence dating, and on how such procedures may improve the accuracy of age determinations.

The goal of the meeting is to promote the discussion regarding radiocarbon and luminescence dating of lime plaster/mortar from archaeological sites and historical architectures, and thus to develop the application of these methods to the study of cultural heritage. Therefore, we welcome contributions regarding analytical methods that address the chemical and physical properties of anthropogenic carbonates, including (but not limited to) FTIR and Raman spectrometry, XRD, XRF, EXAFS, cathodoluminescence, SEM-EDS, electron diffraction, stable isotopes analysis, and thin section petrography; contributions about procedures for carbon recovery and AMS measurements (including organics embedded in lime binders), and on protocols for luminescence measurements. Site reports that present mere lists of radiocarbon/luminescence dates without further methodological discussion will NOT be accepted.

Presentations will be delivered in three sessions followed by an open discussion, according to this preliminary schedule:

Thursday, October 25

  • Session 1: Characterization of anthropogenic carbonates (keynote speaker: Gilberto Artioli)
  • Session 2: Radiocarbon dating (keynote speaker: Elisabetta Boaretto)
  • Poster session
  • Visit to the Institut de Recherche sur les Archéomatériaux-Centre de Recherche en Physique Appliquée à l'Archéologie (IRAMAT-CRP2A), UMR 5060 CNRS, Université Bordeaux Montaigne

Friday, October 26

  • Session 3: Luminescence dating (keynote speaker: Petra Urbanová)
  • Open discussion
  • Meeting dinner

Saturday, October 27 will be dedicated to an excursion in the surroundings of Bordeaux.


We look forward to seeing you in Bordeaux in October!
