Summary: This study presents the first accurate record of Messinian Resedimented Gypsum in the forearc and back-arc basins connected to the Calabrian-Peloritan orogen, using a multidisciplinary approach to analyze the gypsum deposit in Benestare, Southern Italy. The study reveals similarities in petrographic features, fluid inclusions, organic matter, and Strontium isotopic values between the gypsrudite and branching-like facies, suggesting a strong connection with the global Ocean and reduced freshwater input. The deposit originated from the dismantling of selenite crystals related to the Messinian Salinity Crisis through gravitational collapse due to local controlling factors.

Summary: This study conducted stable isotope analysis to investigate dietary niche turnover of five equid species in the Linxia Basin, northwestern China, during a critical phase in their evolution. The results revealed that Proboscidipparion pater mainly fed on C3 grasses while Cremohipparion licenti and Sivalhippus platyodus may have been mixed feeders. However, Cremohipparion licenti and Sivalhippus platyodus went extinct due to climatic changes. Additionally, Proboscidipparion sinense showed a stronger grazing preference compared to coexisting Equus eisenmannae.

Summary: A study reveals a significant earthquake occurred in the early 15th century along the Incapuquio Fault System, causing substantial net slip and posing potential seismic hazards to surrounding communities. This seismic event may also be linked to the collapse of the Chiribaya civilization. Additionally, the forearc in South Peru experiences a complex pattern of permanent strain, with evidence of various deformation processes in close proximity.

Summary: The basement of the Tokyo metropolitan area consists of the Miocene-Pleistocene forearc basin fills that are well exposed around Tokyo Bay, especially on the Miura and Boso peninsulas. The deposits on these peninsulas provide a type stratigraphy for other equivalent sedimentary sequences in the northwest Pacific, but their stratigraphic markers have not been fully utilized to understand the Kurotaki unconformity, which is a basin-wide unconformity between the Miura and Kazusa groups. Our study used correlations among Pliocene vitric tephra beds to better understand the stratigraphy and erosional surfaces in the Miura and Boso regions.

Summary: The offshore Tumbes-Guayaquil forearc basin in Northern Peru-Southern Ecuador exhibits evidence of large-scale gravity-driven deformation systems during the Late Neogene-Quaternary period. The sediments in the basin are detached and decoupled from the underlying accretionary prism systems. This anomalous gravity tectonics can be attributed to a combination of tectonostratigraphic features and overpressured shales.

Summary: The Fucino Basin in central Apennines, Italy, is a major Pliocene-Quaternary non-marine 'extensional col lapse basin' bounded by seismogenic faults that generate strong earthquakes. The basin is an overall dual polarity half-graben with two separate fault-driven depocentres and progressive accumulation of throw without significant fault lengthening, suggesting a different mechanism for fault growth.

Summary: Evidence from landscape evolution can provide important constraints for understanding past geodynamic processes. However, uncertainties in topographic reconstructions have limited the accuracy of such evidence. In this study, we present the rock uplift histories for three catchments in southern Italy, which suggest that the uplift rates were high from 30 to 25 million years ago, declined gradually until around 15 million years ago, and then abruptly increased around 1.5-1.0 million years ago. These uplift rates do not match the forearc's subduction velocity record, indicating that other factors were responsible for the uplift. We propose that the uplift history reflects the establishment and destruction of an upper-mantle convection cell.

Summary: Possible young analogues for the regionally extensive unconformities in the Witwatersrand Supergroup can be found in the South Island of New Zealand. These unconformities in New Zealand show a similar progression from unconformity surface to conglomerate to sandstone to mudstone, like the auriferous reef horizons in Witwatersrand. The hosting sedimentary basins in the South Island have different alluvial gold budgets and display various unconformities related to subsidence and sea level changes.

Summary: The interplay between high-frequency relative sea-level changes and regional uplift leads to the formation of marine terraces with variable topography and gradient due to tectonics and wave erosion. These settings result in the development of subaerial unconformities during both transgressive and forced regressive stages of the sea-level curve. Additionally, tectonic uplift causes the formation of steep coastal profiles and the deposition of shallow-marine wedges during highstand and lowstand stages, recording the uplift of coastal areas.

Summary: This study provides new insights into the relationship between shale mobility and fluid migration in the offshore western Niger Delta. The results suggest that shale tectonics initiated early in the evolution of the region, persisting throughout the Neogene and Quaternary. The presence of mud volcano systems indicates early shale mobilisation in response to overpressure and their potential role as pressure release conduits.

Summary: This work examines the tectonic significance of the Rossano-San Nicola Fault Zone (RSFZ) in southern Italy and its impact on the Crotone Basin. The RSFZ experienced multiple phases of tectonic activity, including contraction and extension, which influenced the development of the Crotone Basin and its gas potential. This study also reveals the first example of a gas field sealed by a large mass-transport complex. The research provides valuable insights into the geological history and prospects for gas generation in southern Italy.

Summary: Seafloor methane emissions, caused by the release of methane from gas hydrate and free gas through the collapse of sediment accumulations on continental slopes, have significant effects on Earth's climate and ocean chemistry. This study highlights the importance of collapsing sediment accumulations as pathways for gas migration, resulting in seafloor emissions. The observed emissions in the study region are three times greater than estimates for the entire US North Atlantic margin, indicating the significance of collapsing sediment accumulations for ocean carbon cycling. Similar outgassing systems exist on other sediment-laden continental slopes.

Summary: The Sciacca basin in southwestern Sicily hosts the Sciacca Geothermal Field, which contains hot springs with mantle gasses. Recent seismic data and profiles reveal active fluid-related features in the nearshore area between Capo San Marco and Sciacca, indicating the presence of a single onshore-offshore geothermal field covering an area of at least 70 km(2). This geothermal field developed in a tectonically active zone, associated with the Sciacca Fault System, and has been active since the lower Pleistocene.
