The marbles exploited between Vitulano and Cautano (Benevento province, Campania region, Italy), have been widely utilized (at least from the 18th to the beginning of the 20th century) in several important monumental buildings of the region, due to their good properties and peculiar aesthetic qualities. They are limestones deriving from the filling of palaeo-cavities, carved into an emerged Cretaceous calcareous platform, by calcareous breccias, bauxite and alabastrine deposits. Such cavities are the result of both jointing and karst processes. The studied outcrops of the Vitulano Marbles are affected by a complex joint pattern in terms of attitude and spacing, which results in rock blocks highly variable in volume. Regarding the mineralogical composition, calcite is definitely predominant whereas the insoluble residue is constituted by low amounts of dolomite, bohemite, ematite and kaolinite. The petrophysical characterization put in evidence fairly good geomechanical properties, only partly affected by the geostructural anisotropy of the rock.
