Space and time in the tectonic evolution of the northwestern Iberian Massif: Implications for the Variscan belt [PDF]
, 2007 Recent advances in geochemical studies of igneous rocks, isotopic age data for magmatism and metamorphism, quantitative pressure-temperature (P-T) estimates of metamorphic evolution, and structural geology in the northwestern Iberian Massif are integrated into a synthesis of the tectonic evolution that places the autochthonous and allochthonous ...

Cadomian metabasites of the Eastern Pyrenees revisited
Geologica Acta, 2023 This study presents a new geochemical, petrological, and geochronological U-Pb dataset from Ediacaran metabasites and associated rocks of the Canigó and Cap de Creus massifs, Eastern Pyrenees. Metabasites are composed of calcic amphibole + plagioclase +

Leveraging Roadless Areas to Support Strict Protection in the EU
Diversity and Distributions, Volume 32, Issue 6, June 2026.ABSTRACT Aim Strictly protected areas exhibit lower levels of disturbance to habitats and species and are central to biodiversity conservation. Yet only 4% of the EU's land is currently placed under strict protection, far below the 10% target set by the EU Biodiversity Strategy for 2030. This study examines the potential of roadless areas to contribute

Strain partition in synkinematic granitoids intruded in a transpressive setting (Sanabria, Central Iberian-Zone, Iberian Massif) [PDF]
, 2007 The Sanabria Lake plutons, located in the Central Iberian Zone of the Iberian Massif, intruded in a dextral strike-slip fault bridge under transpressive conditions. The deformed zone underwent a strain partitioning process, so that large folded domains

Ediacaran ophiolites from the SW Iberian Massif
[ES] El basamento cadomiense del SW del Macizo Ibérico contiene varias unidades máficas – ultramáficas de naturaleza ofiolítica. La Ofiolita de Calzadilla y la Ofiolita de Mérida tienen protolitos formados a c. 602 Ma y 594 Ma, respectivamente. La composición de sus rocas máficas permiten interpretarlas como ofiolitas de zona de supra-subducción ...
