Analytical Characterization of the Geomaterials Used in the Construction of the Late Antique Wall in Emerita Augusta (Mérida, Spain)

A comprehensive analysis of the geomaterials used in the Late Antique wall of Emerita Augusta (Mérida, Spain) reveals traditional Roman construction techniques and material provenance. The study identified granite types and confirmed the use of fully carbonated lime as a binding agent in mortars, consistent with historical practices. Using advanced techniques such as XRD, XRF, ICP-MS, TGA-DTA, and SEM, researchers characterized mineralogical, textural, and geochemical properties, providing critical insights for the preservation and restoration of this UNESCO-listed heritage site. These findings enhance understanding of late antiquity construction methods and support evidence-based conservation strategies.
