Characterization and origin of the Mn-rich patinas formed on Lunéville château sandstones

Data sets

XANES, XRD and Raman-spectroscopy data on Mn-rich phases on Lunéville château sandstones (patinas and bulks) Laure Gatuingt, Stéphanie Rossano, Jean-Didier Mertz, Chloé Fourdrin, Olivier Rozenbaum, Quentin Lemasson, Solenn Reguer, Nicolas Trcera, and Bruno Lanson

Short summary
Dark patinas rich in manganese (Mn) developed on several sandstones of the Lunéville château (France) contrasting with the general yellow color of the building. The characterization of the Mn compounds in the patinas, but also in the building stones, allowed us to propose a model for the patina formation based on the dissolution of the Mn phases initially present in the stone bulks. The results obtained in this study might enlighten processes occurring on other buildings or in natural settings.
