Short summary
Short summary
Considering the structural complexity related to the internal architecture of active and capable faults, seismic hazard may be linked to different fault attributes depending on the fault domain crossed by a linear infrastructure. We propose a structural geology-based approach for the preliminary study of the area potentially affected by earthquake-induced surface ruptures during infrastructural design, based on the geometric relationships between the active fault and the infrastructure itself.

This study addresses the tectonic evolution of the seismogenic Monti Martani Fault System (northern Apennines, Italy). By applying a field-based structural geology approach, we reconstruct the evolution of the stress field and we challenge the current interpretation of the fault system in terms of both geometry and state of activity. We stress that the peculiar behavior of this system during post-orogenic extension is still significantly influenced by the pre-orogenic structural template.

Smøla island, in the mid-Norwegian margin, has complex fracture and fault patterns resulting from tectonic activity. This study uses a multiple-method approach to unravel Smøla's tectonic history. We found five different phases of deformation related to various fracture geometries and minerals dating back hundreds of millions of years. 3D models of these features visualise these structures in space. This approach may help us to understand offshore oil and gas reservoirs hosted in the basement.

Short summary
The Earth's surface is commonly characterized by the occurrence of fractures, which can be mapped, and their can be geometry quantified on digital representations of the surface at different scales of observation. Here we present a series of analytical and statistical tools, which can aid the quantification of fracture spatial distribution at different scales. In doing so, we can improve our understanding of how fracture geometry and geology affect fluid flow within the fractured Earth crust.

This study focuses on the impact of deformation bands on fluid flow and diagenesis in porous sandstones in two different case studies (northern Apennines, Italy; Provence, France) by combining a variety of multiscalar mapping techniques, detailed field and microstructural observations, and stable isotope analysis. We show that deformation bands buffer and compartmentalize fluid flow and foster and localize diagenesis, recorded by carbonate cement nodules spatially associated with the bands.

RA138 is a new reference material for U–Pb dating of carbonate samples via laser ablation inductively coupled plasma mass spectrometry. RA138 exhibits variable U–Pb ratios and consistent U content, resulting in a precise isochron with low uncertainty. Isotope dilution thermal ionization mass spectrometry analyses fix a reference age of 321.99 ± 0.65 Ma. This research advances our ability to date carbonate samples accurately, providing insights into geological processes and historical timelines.

Short summary
A structural-geochronological approach helps to unravel the Zuccale Fault's architecture. By mapping its internal structure and dating some of its fault rocks, we constrained a deformation history lasting 20 Myr starting at ca. 22 Ma. Such long activity is recorded by now tightly juxtaposed brittle structural facies, i.e. different types of fault rocks. Our results also have implications on the regional evolution of the northern Apennines, of which the Zuccale Fault is an important structure.
