Summary: In this paper, a structural model of the Sierra de Atapuerca is presented, which is located in the transition zone between the Iberian Range and the southwestern Basque Cantabrian Basin in NW Spain. The current structure of this zone is the result of an Alpine tectonic inversion of a previous Mesozoic extensional configuration, inherited from late Hercynian faults.

Summary: The Aptian sedimentary deposits of the Castro Urdiales area in north Spain record a post-OAE1a episode of disoxia/anoxia. The lower to upper Aptian black lutites and marlstones of the Castro Urdiales area are correlated with other Aptian sections of the Basque-Cantabrian Basin and southeastern France. Prior to the oxygen deficient episode, glauconite-and-ostreid facies were deposited during the Gutiolo volcanic event. The volcanism correlates in part with the Cretaceous superplume eruptions.

Summary: This study integrates classic and modern geochemical and geochronological datasets with the current tectonic knowledge of the Pyrenean fold belt and the Basque-Cantabrian Basin to discuss the fluid history in extensional and compressional sedimentary basins along the Iberian-Eurasian plate boundary. The research findings highlight the dominance of late Hercynian fluid systems by Carboniferous-early Permian magmatic intrusions and the occurrence of contact metamorphism processes during the Mesozoic extension. The Alpine compressional fluid history shows the increasing influence of meteoric fluids as the foreland basin became overfilled. Rating: 5/10.

Summary: Oceanic red beds (ORBs) in the Basque-Cantabrian Basin of northern Spain show exceptional features in Upper Cretaceous and Danian deep-marine deposits. The color variations and sedimentation rates indicate the oxidizing activity of deep, cold-water masses. The presence of hematite as the main staining agent in the red beds suggests a slow sedimentation process in oxic environments.

Summary: This study in the Cenozoic Ferreira basin of NW Spain investigates the red clay unit and granitic basement rocks, showing that the lateritic red clays are derived from residual weathering of mafic +/- intermediate rocks and were likely formed under tropical climate conditions around 70 million years ago. Subsequent tectonic events and hydrothermal activity remobilized the red clays, deposited them in faulted grabens, and affected them along with the adjacent basement granites. This study emphasizes the interplay of different geological processes in small continental basins.

Summary: This work explores the application of consumer-grade virtual reality hardware and software to the analysis of digital outcrop data. The results show that fault statistics obtained using VR analysis are broadly equivalent to those acquired from conventional flat panel displays. However, VR analysis incurs censoring of finer fault traces due to limited resolution of the outcrop model textured mesh.

Summary: The study reveals the presence of vertical joints perpendicular to bedding on the Pietrasecca Anticline in central Apennines, Italy, suggesting that these joints may have formed before folding and are related to a foredeep environment. Additionally, the intensity of joints along the anticline does not correlate with structural position, indicating that the joints are not necessarily syn-folding deformation structures.

Summary: This study presents the results of a rockfall trajectory study performed on Mt. Catiello in southern Italy using a multi-methodological approach that integrates different types of remote sensing data and techniques. Ground-truth data generated from virtual outcrop models were used to reconstruct the in-situ fractured rock mass attributes and simulate rockfall trajectories. The proposed approach is consistent with the ground-truth data and can be applied to other areas with similar geological features but higher levels of exposure and vulnerability.

Summary: South Matese in Italy is an active extensional area with CO2 outgassing and earthquakes. This study focuses on understanding the pulverization process of dolostone in the region. The pulverized dolostone is finely comminuted and retains primary structures. The formation of pulverized dolostone may be due to the sudden decompression of pressurized CO2 gas during earthquakes. The research findings provide insights into chemical-physical processes related to CO2 storage in seismically active areas.

Summary: During the Early Cretaceous, Adria experienced an acceleration in subsidence after the Africa-Europe convergence, which has been puzzling due to the lack of faults associated with crustal stretching in the central Mediterranean area. However, a syn-sedimentary extensional fault system in southern Italy has been discovered, indicating the largest exposed extensional system of Adria during the Aptian-Cenomanian period. The extensional tectonics in Adria can be explained by a slab pull mechanism caused by the subducting Neotethys Ocean.

Summary: We investigate the timing and mode of the Circeo thrust formation and its subsequent extensional reactivation in the central Apennines using a combination of structural analysis, isotopic analysis, seismic interpretation, and other methods. Our results show that the forelandward migration of the foredeep-thrust system occurred at variable velocities, which were synchronous with the opening of back-arc basins and quiescent periods.

Summary: The rapid identification and modeling of faults responsible for major earthquakes plays a crucial role in understanding the evolution of potentially destructive seismic events. This becomes even more challenging when dealing with buried thrust faults located in offshore areas. In the case of the Ml 5.7 and M-L 5.2 earthquakes that occurred along the Apennines compressional front offshore the northern Adriatic Sea, geodetic observations and seismological data provide valuable insights into the rupture characteristics of a 15 km long fault. The potential activation of longer fault segments with higher magnitudes and larger surface faults is a concerning scenario that requires further investigation, considering the tsunamigenic potential and possible impact on human communities and infrastructure.
