Summary: The trace element and isotopic compositions of exhumed high-pressure mafic rocks provide important information on chemical processes in subduction zones. In this study, the boron isotopic composition of eclogitic mafic rocks from the Voltri Massif, Italy, was investigated to understand oceanic inheritance and subduction-related processes. The results suggest that the negative 811B signatures in eclogites are mainly caused by dehydration processes during subduction, while positive 811B signatures are likely inherited from oceanic sources or influenced by fluids released by serpentinites.

Summary: The Moglio-Testico Unit is considered a fragment of oceanic cover whose sedimentary evolution reflects part of the oceanic lithosphere approaching the subduction zone. Structural analysis combined with thermobarometry suggests that this unit underwent polyphase deformation history under High Pressure-Low Temperature metamorphic conditions during its underthrusting, accretion into the Alpine wedge, and subsequent exhumation.

Summary: The study of SW Piemonte suggests the presence of a regional transfer zone (SWAT) recording Oligocene-Miocene activity and the development of GVZ/SWAT and PF/IBF structures. The postcollisional evolution of the SW Alps is recorded by the TPB basin, influenced by transpressive faults and Apennine thrusts stacking Ligurian units. This correlation between the Alps and the Apennines highlights their kinematics and tectonic control on the same syn-orogenic basin.

Summary: Deep-seated gravitational slope deformation (DsGSD) is an important geological-geomorphological feature that has attracted scientific attention. Through detailed fieldwork and integration of various analyses, typical DsGSDs were identified, which may have caused large-scale landslides in the area. Further investigation is needed to understand the mechanisms and implications of these DsGSDs.

Summary: The formation of the Central Andes is attributed to the changing geometry of the subducted Nazca plate, resulting in pulses of tectonic shortening and the growth of the Altiplano-Puna Plateau. Mechanically weakening of the South America plate, such as through mantle lithosphere delamination and weakening of foreland sediments, enhances the intensity of the shortening events.

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: In certain sectors of water resources management, the progress of the digital revolution is hindered by factors such as costs, lack of digital expertise, and resistance to change. This project aims to examine the feasibility of using an open, cost-effective, and replicable digital ecosystem for lake monitoring to address the issue of incomplete integration of information. By utilizing cloud-based technology and an Automatic High-Frequency Monitoring System (AHFM) built with open hardware and software components, the system will be tested and validated in a real-life scenario, integrating historical databases and evaluating the performance of the AHFM system.

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.
