Linking deep-time magmatism to present-day lithospheric architecture through isotopic and elemental mapping Open
Probing the deep lithosphere remains a key objective in earth sciences. The present-day lithosphere architecture is a terminal, time-integrated image shaped by long-term geological processes, among which magmatism plays a crucial role. Con…

Sublithospheric reworking of the continental crust Open
The formation of the continental crust is driven by an igneous process in which mantle-derived magmatism is incorporated into the overlying crust. Continental collision represents a major lithospheric event, where crustal destruction and g…

A post-collisional batholith from Southern Iberia rooted in the Earth's mantle: Los Pedroches batholith Open
The Los Pedroches batholith (SW Spain) is one of the most salient igneous alignments of the Iberian massif. The batholith is considered one of the best examples of post-collisional batholiths of Iberia and is dominated by a biotite granodi…

Mafic microgranular enclaves (MMEs) trace the origin of post-collisional magmas Open
Mafic microgranular enclaves (MMEs) are a ubiquitous feature of post-collisional magmatism, receiving much attention among earth scientists over the last decades. While recent advances point to the large-scale involvement of the lithospher…

Post-collisional batholiths do contribute to continental growth Open
Post-collisional voluminous silicic magmatism is represented in most orogens across the world in the form of large granodiorite batholiths and minor intermediate and mafic intrusions, postdating 5-30 Ma the age of the collisional paroxysm …

Visean high-K mafic–intermediate plutonic rocks of the Ossa–Morena Zone (SW Iberia): implications for regional extensional tectonics Open
Field relationships and new U–Pb geochronology data indicate a temporal link between the diverse high-K mafic–intermediate magmas of the Ossa–Morena Zone (OMZ). Ages of c. 338–335 Ma for the Vale de Maceiras gabbro and the Campo Maior micr…

Changing Carboniferous Arc Magmatism in the Ossa-Morena Zone (Southwest Iberia): Implications for the Variscan Belt Open
Carboniferous magmatism in southwestern Iberia was continuously active for more than 60 m.y. during the development of the Appalachian-Variscan belt of North America, North Africa and Western-Central Europe. This collisional orogen that re…
