(a) 3D tomography of the pillar; (b) 3D view of tomographic slices; (c) thin section of the Tramezzario showing its textural characteristics, dominant texture: grainstone; (d) thin section of the Pietra Cantone, dominant texture: mudstone. The thin sections were impregnated with blue epoxy to better visualize the pore space. 3D data represented with Voxler-3D geologic and scientific modeling software (Golden Software), http://www.goldensoftware.com/.
