“…In the present study, we used cubic stone specimens of 50 ± 5 mm of edge ( Figure 1 ). The type of rock used in this work can be classified as dolomite—known as limestone, from Boñar, Spain—a fine-grained, crystalline, and highly dolomitized rock [ 8 , 9 , 10 ]. It presents sparitic limestone filling in fissures and cavities.…”

The historical stone heritage that we inherit must be passed on to future generations, not only in the same conditions that we found it but, if possible, in better ones. Construction also demands better and more durable materials, often stone. The protection of these materials requires knowledge of the types of rocks and their physical properties. The characterization of these properties is often standardized to ensure the quality and reproducibility of the protocols. These must be approved by entities whose purpose is to improve the quality and competitiveness of companies and to protect the environment. Standardized water absorption tests could be envisaged to test the effectiveness of certain coatings in protecting natural stone against water penetration, but we found that some steps of these protocols neglect any surface modification of the stones, and hence may not be completely effective when a hydrophilic protective coating (i.e., graphene oxide) is present. In this work, we analyze the UNE 13755/2008 standard for water absorption and propose alternative steps to adapt the norm for use with coated stones. The properties of coated stones may invalidate the interpretation of the results if the standard protocol is applied as is, so here we pay special attention to the characteristics of the coating applied, the type of water used for the test, the materials used, and the intrinsic heterogeneity of the specimens.

“…The Boñar Formation is mainly formed of carbonate rocks (limestones and dolomites) intercalated with shales and marlstones with thickness of approximately 300 m. This succession indicates that the formation was deposited in terrigenous-carbonated mixed platforms with shallow subtidal and intertidal areas on open shelf depositional environments (Gómez Fernández et al 2003;Herrero-Hernández & Gómez-Fernández 2012;Suárez-González et al 2016). The palaeogeography of the study area has not been investigated in details due to the limitations of outcrops.…”

Abstract:The subsurface sedimentary succession of the Iberian Trough, Spain was examined using geophysical t echniques (analogue seismic profiles) and inverse distance weighted (IDW) interpolation algorithm implemented in a gvGIS open source software. The results showed that the Late Cretaceous succession is divided into two depositional sequences: DS-1 (Late Albian-Middle Turonian) and DS-2 (Late Turonian-Campanian). From the analogical seismic sections, digital data and quantitative isopach maps for DS-1 and DS-2 were obtained. The new isopach maps obtained for the DS-1 sequence showed that the deeper sectors of the basin were located to the northeast and the proximal ones to the southwest. The palaeoshoreline was inferred to be situated in the N 150 direction. Across and parallel to this direction several blocks were delimited by faults, with a direction between 30 N and N 65. The thickness of the sediments in these blocks varied in direction NW-SE, with subsidence and depocentres in hangingwall and uplift in the footwall. These variations may have been related to active synsedimentary faults (e.g., Boñar and Yugueros Faults). In the DS-2 sequence, a lineament separated the smaller thicknesses to the southwest from the larger thicknesses (up to 1400 m) to the northeast. This lineament had an N170 orientation and it indicated the position of the palaeoshoreline. In the isopach map for DS-2 there were two groups of lineaments. The first showed a block structure that was limited by N100-120, they were foundering toward the S and had large thicknesses (depocentres), and rose towards the N, where there were smaller thicknesses. The second group of lineaments had a N 50-65 direction and, in this case, they had a similar interpretation as the one in DS-1. The maps obtained are of great help for geologists and permit better understanding of the geological setting and stratigraphic succession of the Late Cretaceous of the Iberian Trough.
