Petrophysical and geochemical characterization of the late-variscan Santa Eulália Plutonic Complex (Ossa-Morena Zone, Portugal) [PDF]
, 2012 The Santa Eulália Plutonic Complex (SEPC) is a calc-alkaline granitic body located in the northern part of the Ossa Morena Zone, composed by a medium- to coarse-grained pink granite (G0 group) involving large elongated masses of mafic (gabbroic) to ...

Exhumation of the Sierra de Cameros (Iberian Range, Spain): constraints from low-temperature thermochronology [PDF]
, 2008 We present new fission-track and (U–Th)/He data from apatite and zircon in order to reconstruct the exhumation of the Sierra de Cameros, in the northwestern part of Iberian Range, Spain. Zircon fission-track ages from samples from the depocentre of the

Early evolutionary history of the seed
Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

On the Upper Ordovician unconformity in the Pyrenees: New evidence from the La Cerdanya area
Geologica Acta, 2007 In recent years, contradictory reports about whether or not an unconformity exists at the base of the Upper Ordovician succession of the Pyrenees have been made.

BSGF - Earth Sciences Bulletin, 2020 To provide a better picture of the active geodynamics along the Variscan suture zones during the late collisional stage (particularly regarding the evolution of the orogenic system towards HT conditions), we focused here on vaugnerites, which consist of ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Melt migration in partially molten rocks is commonly described by porous flow models controlled by the hydro‐mechanical compaction length, which effectively explains melt extraction at mid‐ocean ridges. However, this framework cannot account for the paradoxical accumulation of small melt fractions into rhythmic leucosome–melanosome bands in ...

Tectonics, Volume 45, Issue 5, May 2026.Abstract The paleomagnetism of Miocene calc‐alkaline volcanics and sediments from Sardinia has firmly showed that the Corsica‐Sardinia microplate rotated 50°–60° counterclockwise (CCW) with respect to Europe between 21 and 15 Ma, during its drift from the Provencal margin. However, Permian to Eocene rocks from central‐south Sardinia revealed higher (up
