Evaluation of Calcarenite Degradation by X-ray Photoelectron Spectroscopy Analysis inside the Rupestrian Church of San Pietro Barisano (Matera, Southern Italy)

X-ray photoelectron spectroscopy (XPS) analysis reveals distinct degradation products on the calcarenite surfaces of San Pietro Barisano, a rupestrian church within Matera's UNESCO-listed Sassi district. This study identifies biotic and abiotic degradation indicators, offering a diagnostic framework for preserving such heritage sites. By comparing degraded samples to reference calcarenite, researchers link findings to local environmental factors and historical context, enabling targeted conservation strategies under the National Smart Cities research project.
