Evidence for Lithospheric Mantle Uniformity Beneath Cratons
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.Abstract Cratons are characterized by thick mantle roots that have experienced high degrees of partial melting, resulting in a cold, strong, and buoyant mantle compared to its oceanic counterpart. The extent of chemical variability within cratonic roots, the role of cratons in insulating the mantle over time and subsequent triggering of continental ...

Imaging spectrometry and the Ronda peridotites
In Chapter 2, the results of detailed geologic mapping of sedimentary strata of the Subbeticum of Ronda are presented including a stratigraphic description of several sections near Ronda, El Burgo, Ardales, Teba, and Arriate in the Ronda-Málaga area. These are used to develop time-facies profiles on basis of which the paleogeography is reconstructed ...

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.Abstract At mid‐ocean ridges, the mantle temperature and composition, and the lithosphere thickness control the melting conditions, which influence the feeding and structure of the neo‐volcanic areas. We present a study of the eastern intersection between the Romanche transform fault (TF) and the adjacent southward segments of the Mid‐Atlantic Ridge ...

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.Abstract Interactions between mantle plumes and mid‐ocean ridges create considerable spatial variation in composition along ridge axes. What is less well known is the temporal variation in MORB compositions along single mantle flow lines. IODP Expeditions 390/393/390C/395E recovered basaltic basement from seven sites along a flow line, the South ...

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.Abstract Subduction initiation is fundamental to our understanding of plate tectonics. However, the mechanisms and processes of subduction initiation, especially at passive continental margins, are poorly understood due to limited geological records.
