The study focuses on the provenance of limestone utilised in the construction and restoration of the Batalha Monastery in Portugal. A novel multi-analytical approach was employed, combining sample collection, field survey, and various analyses including thermogravimetric analysis (TGA) and X-ray fluorescence spectroscopy. The research aimed to obtain petro-geochemical data from the stones to aid in conservation strategies for the monastery. Twelve stone fragments were collected from different parts of the monastery with permission from relevant authorities. Additionally, ancient quarries mentioned in literature were located and sampled. Petrographic and geochemical analyses were conducted using techniques such as TGA, XRD, OM, SEM, and ED-XRF.
Results revealed correlations between specific quarries and different sections of the monastery, confirming the attribution of quarry sources for the building materials. Petrographic analysis of thin sections showcased distinct features such as oolites, calcite crystals, and fossils, providing insights into the composition of the limestone. The study’s findings offer valuable information for future conservation and restoration efforts, aiding in the selection of stones with similar properties to maintain the historical monument’s integrity.
To further validate the results, future analyses using inductively coupled plasma-mass spectroscopy (ICP-MS) are planned. The research contributes to understanding the historical quarries and materials used in the monastery’s construction and restoration. Overall, the study’s comprehensive approach sheds light on the geological aspects of the Batalha Monastery, providing essential data for preservation and potential restoration interventions.
