Summary: Salt-bearing basins are commonly deformed due to gravity mechanisms and regional tectonics, with the study area in the eastern part of the Herodotus Basin showing deformation associated with the flow of Messinian salt deposited during the Messinian Salinity Crisis. The research reveals significant thickness variations of the salt sequence and overlying sediments, as well as distinct salt-tectonic structural provinces characterized by different deformation styles. The compressional thickening of the Messinian salt driven by gravity mechanisms results in the absence of a bathymetric step on the seafloor in the western side of the study area.

Summary: High-resolution multichannel seismic transects were used to investigate the dynamic mechanism of the Oligocene tectonic evolution in the West Philippine Basin. The study found evidence of weaker and unstable magma supply in the Central Basin Fault rift after the major spreading period, as well as indications of transtensional faulting and magmatic accretion. This suggests that the Oligocene tectonic evolution in the basin was driven by a combination of magmatic accretion and transtensional tectonics.

Summary: The study revealed active out-of-sequence thrusting in the Imbricated Molasse Basin near the Alpine front thrust, indicating significant impact on the local structural evolution. Stress data from boreholes confirmed the current activity of these thrusts, with geomechanical modeling supporting a thrust regime in the region. The observation of active thrusting in the area aligns with Pleistocene out-of-sequence thrusts in the external tectonic units of the Eastern Alps.

Summary: In this study, a crustal scale model for the Neo-Tethys margin in the Northern Calcareous Alps was obtained by restoring regional cross-sections of carbonate platforms. The thermal evolution of the margin was modeled and a detailed timeline for the evolution was established. The study suggests that salt-floored carbonate platforms can be used to characterize the margin's evolution.

Summary: Understanding the development of syn-rift carbonate systems is complex, and their facies distributions can sometimes be difficult to predict due to key factors such as tectonics, eustasy, palaeogeography and climate. The study in SE Dahra Platform demonstrates that synsedimentary faults control reservoir architecture and predict heterogeneous distributions of carbonate facies, with local tectonic deformations and sea-level changes being primary controls on platform geometry and facies distributions.

Summary: This study investigates the influence of preexisting basement structures on the formation and evolution of rift faults. The results show that the geometry of rift faults is controlled by the mechanical contrast between tectonometamorphic units separated by ductile shear zones. The findings provide insights into the 3-D relationship between inherited structures and subsequent fault reactivation.

Summary: A dense grid of high-resolution multichannel seismic reflection profiles is used to delineate the stratigraphic and structural architecture of the Anamur-Kormakiti zone, revealing the presence of two arcuate sinistral strike-slip fault zones and a narrow NNW-SSE trending zone with positive flower structures, indicating a rotational stepover between oppositely moving strike-slip fault zones. The regionally extensive strike-slip fault zones were largely developed during the Pliocene-Quaternary in response to the westward escape of the Aegean-Anatolian Microplate following the collision and suturing of the Arabian Plate to the Eurasian Plate during the end of Miocene-Early Pliocene.

Summary: The Outer Cilicia Basin evolved as an asymmetric piggyback basin on the hanging wall of a large thrust culmination during the uppermost Messinian-Quaternary, with a major backthrust and smaller splays developing in the southern sector. E-W trending positive flower structures and extensional fault zones define the tectonic framework of the basin, with distinct regional folds likely cored by deep-seated blind thrusts.

Summary: Fault barriers are important for studying seismic hazard in regions of intense brittle deformation, and the interaction between fault sets affects their seismogenic behavior. The Granada Basin is affected by two sets of faults, with one set acting as a barrier, limiting the extent and magnitude of earthquakes. The presence of preexisting fractures facilitates the propagation of earthquakes.

Summary: The study investigated the unique structural patterns within a km-scale shear zone, emphasizing the coupled deformation between ultramafics and host rocks. Results from numerical modeling showed that the deformation and fold development of inclusions were dependent on viscosity ratio, shear strain, and inclusion aspect ratio. The study highlights the importance of progressive deformation in explaining complex structural patterns in shear zones without requiring multiple deformation phases.

Summary: The study focuses on the geological samples from the Cima di Gagnone area in the Central Alps, revealing heterogeneous metamorphic conditions in rocks of different composition and rheology. The research results show that the metasediments generally experienced medium pressure and medium temperature conditions, but samples near ultramafic lenses recorded significantly higher conditions. Additionally, the study also identifies local melt/fluid interaction, as well as deformation-driven pressure and temperature variations within the rocks.

Summary: The formation of shear zones is crucial for understanding crustal deformation and the evolution of rifted margins. However, there is often a lack of detailed characterization of the compositional and structural patterns of shear zones, leading to poorly constrained models of shear initiation. This study focuses on the Anzola shear zone and reveals the significant pre-existing heterogeneities related to the composition and deformation structures, suggesting that these heterogeneities are preferential loci for strain localization controlling the initiation and development of rift-related structures in the mid to lower crust of passive margins.

Summary: This petrographic database was created to study the Oligocene-Langhian succession of the Arquata Scrivia area in NW Italy, which includes different marine sedimentary units deposited in the Tertiary Piedmont Basin. The database provides unique information about the petrographic composition of the studied succession, which had not been previously investigated. Petrographic analysis was conducted on samples collected from different parts of each sedimentary unit using a polarized-light microscope. The collected data are presented in quartzfeldspar-lithic ternary plots and can serve as a starting point for future analyses to understand the evolution of the basin on a larger scale.

Summary: This study reassesses the architecture and tectonic history of the Western Alps based on recent knowledge developed at rifted margins. The authors propose a new model where units previously attributed to the internal part of the Brianconnais domain actually belong to the Prepiemonte hyperextended domain. They also suggest an uneven-margin architecture to explain the complexity of the Western Alps. The study provides insights into the kinematic model and orogeny of the region.
