Data sets

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.
