Abstract

This study investigates "Tufo di Viterbo", a natural stone of significant interest in the cultural heritage field widely appreciated as a building material. The mineral composition and crystalline microstructures of Viterbo Tuff were analyzed using X-ray Diffraction (XRD) and Micro-Raman scattering (MRS) techniques. This work provides valuable information that could be helpful for the artistic heritage preservation and environmental science communities, potentially enabling the formulation of enhanced strategies for extending the durability of this important natural resource. Additionally, the comprehensive mineralogical analysis of "Tufo di Viterbo" can provide instrumental evidence supporting or corroborating its natural radioactivity levels, thereby enhancing our knowledge of its geological and environmental significance. This research was carried out as part of the PRIN 2022 PNRR ATHENA project, funded by the European Union through the Next Generation EU initiative.
