Linking Geodetically Resolved Uplift to Long‐Term Orogenic Exhumation in the Southern Alps, New Zealand

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract A limitation in our understanding of the geodynamics of orogenies is the difficulty in resolving the spatial variations in long‐term processes such as exhumation of the crust. Although geodesy can record ground motions to millimeter‐scale precision at high spatial and temporal resolutions, these observations only cover a small fraction of the ...

Secular Evolution of the Seismic Structure of Continental Crust, Archean to Present

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract We summarize the seismic and density structure of continental crust as a function of crustal age and evaluate the secular changes in these physical properties. We subdivide the continental crust into six age provinces, from Archean to Mesozoic‐Cenozoic, and calculate the surface area, mean crustal thickness, volume, mass, and seismic velocity ...

A multidisciplinary study on the location of Roman sites in the southern sub‐plateau of the Iberian Peninsula

open access: yesArchaeometry, Volume 67, Issue 5, Page 1373-1390, October 2025.
Abstract Architectural and engineering elements of the Roman civilization constitute an important cultural heritage. Nevertheless, not all ancient Roman cities and the roads connecting them have been found, mainly because classical geographical sources show a significant lack of precision.

Plume–Lithosphere Interaction and the Role of the Mid‐Lithospheric Discontinuity in Craton Delamination

open access: yesGeophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract We present results from thermo‐mechanical numerical modeling of interactions between thermal, thermo‐compositional, and purely compositional (hydrous) mantle plumes, and a rheologically layered lithosphere containing a mid‐lithospheric discontinuity (MLD). Our simulations show that mantle plume impact can effectively destabilize and delaminate
