  • Near infrared spectra and hyperspectral imaging of medieval fortress walls in Carcassonne : a comprehensive interdisciplinary field study
  • 2016
  • Ingår i: NIR news. - Chichester : IM Publications. - 0960-3360 .- 1756-2708. ; 27:3, s. 16-20

    • A comprehensive study has been launched in the medieval fortress of Carcassonne involving a cooperation between the universities of Umeå and Rennes, and the research institute of IRSTEA of Montpellier. This study aims to combine several spectroscopic techniques in order to resolve archaeological problems related to which raw materials were used during the city wall construction, and also to improve our understanding of the different phases of construction and use of the city walls. This study was also used for elucidating the different qualities and weak points of the applied field methods.

  • Characterization of building materials by means of spectral remote sensing : the example of Carcassonne's defensive wall (Aude, France)
  • 2019
  • Ingår i: Journal of Archaeological Science. - : Elsevier. - 2352-409X .- 2352-4103 .- 0305-4403 .- 1095-9238. ; , s. 396-405

    • Geological and archaeological analysis of stone masonries in standing structures helps reveal information aboutuse of natural resources. At the same time, the study of historical materials is useful for conservators and culturalheritage management. Geochemical and petrographic analysis of building material types is usually done throughdestructive analysis on a few selected samples and can be problematic due to the costs of operations and the sizeof buildings themselves. This paper demonstrates that the combination of hyperspectral imaging portable NearInfrared (NIR) spectroscopy and Energy Dispersive X-ray Fluorescence (ED-XRF) spectroscopy can be useful foranalysing types of raw materials used in distinct construction phases of the inner defensive wall in the citadel ofCarcassonne (Aude, France). Stratigraphic analysis of the architecture, short-range spectral remote sensing andportable ED-XRF measurements were combined in an interdisciplinary approach to classify sandstone elements.The experimental protocol for in situ non-destructive analysis and classification of the masonry types allows theinvestigation of the monument in a diachronic perspective, collecting information to delineate raw materialsvarieties and their use or re-use through time.
