Multidisciplinary approach to revisit the state of activity of a deep‐seated gravitational slope deformation in the frame of the Quaternary geomorphological evolution of the Central Apennines (Italy)

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Abstract Evaluating the state of activity of Deep‐Seated Gravitational Slope Deformation (DSGSD) is a challenge that requires multidisciplinary analytical approaches. This research focuses on the slope‐scale gravitational process, framing the role of the Quaternary morphodynamics of a river valley where multiple DSGSDs coexist, to reconstruct the ...

The Messinian Salinity Crisis Between Italy and Albania: The Peri‐Adriatic Depression and Southern Adriatic Basin Records

Basin Research, Volume 38, Issue 2, March/April 2026.
Basin‐scale correlation of Messinian salinity crisis (MSC) deposits across the Apennine–Albanide foreland basin system integrating outcrop and subsurface data. ABSTRACT We reconstructed the geological evolution of the Albanides during the Messinian salinity crisis (MSC), based on the integration of outcrop and subsurface data from both onshore (peri ...
