The two analyzed rocks in this study are located in the municipalities of Barxeta (Barxeta crema) and Quatretonda (Buixcarro rosa; Mountain range of Buixcarro) in the southern part of the Valencia province. These massive, mostly recrystallised, Campanian limestones (Late Cretaceous, ~70-84 Ma) were deposited on the southern margin of the Iberian plate during the alpine cycle. This zone is characterized by a great tectonostratigraphic complexity and is situated at the limit of the Betic (external Pre-Betic) and the SE Iberian Mountain Belt and, therefore, is less affected by the alpine deformation. Quarrying for architectonic, sculpture and ornamental use began in Roman times (Augustus), but due to present-day exploitation of the quarry it is difficult to identify their old excavation faces. The limestones, thanks to the ease with which they can be worked (scant porosity, uniform grain size, hardness etc.), were especially used for architectonic decoration. In the Valencia Community examples can be found in monuments such as the Claustrillo Alto de Palacio del Abad, within the Cistercian complex of the Monastery of Santa Maria (Valldigna), as in the Cathedral, Lonja, and the Basilica de la Virgen de los Desamparados (Valencia). The petrological characterization of the host rocks has been performed in the laboratory of the Instituto de Restauracion del Patrimonio de la Universidad Politecnica de Valencia. Hence, scanning electron microscopy (energy dispersive x-ray microanalysis, SEM/EDX), Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD) and voltammetry of microparticles were used to determine the chemical and structural composition of the two rock types, Barxeta crema and Buixcarro rosa.
