Experimental Constraints on Hercynian Anatexis in the Iberian Massif, Spain [PDF]

open access: yesJournal of Petrology, 2000
We have studied experimentally the melting relationships of the Ollo de Sapo gneiss (OSG), an important crustal protolith for the Iberian leucogranites, of possible volcanoclastic origin. The results of this study are compared with previously determined PTt paths, allowing us to interpret the mechanisms of melting and granitoid production during the ...

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Cadomian/Pan-African consolidation of the Iberian Massif assessed by its detrital and inherited zircon populations: is the ~610Ma age peak a persistent Cadomian magmatic inheritance or the key to unravel its Pan-African basement?

open access: yesGeologica Acta, 2022
This work assessed the age distribution of Cadomian/Pan-African orogenic events (550-590 and 605-790Ma, respectively) in several zones of Iberian Massif by means of detrital and inherited zircon analysis compilation. Detrital zircon age spectra show that

Polyphased rare-element magmatism during late orogenic evolution: geochronological constraints from NW Variscan Iberia

open access: yesBSGF - Earth Sciences Bulletin, 2022
Rare-element granites and pegmatites represent important sources of raw materials for “clean, green and high technologies”, such as lithium and tantalum, for example.

Phylogeny of the ant genus Aphaenogaster (Hymenoptera: Formicidae) in the Iberian Peninsula, with the description of a new species

open access: yesSociobiology, 2018
A phylogenetic tree of the Iberian Aphaenogaster species - except for A. splendida (Roger) - and a key to the worker caste of all Iberian Aphaenogaster species are proposed. The position of A. striativentris Forel and A.

Advances in the modeling of the Iberian thermal lithosphere and perspectives on deep geothermal studies

open access: yesGeothermal Energy, 2023
Renewable energy sources are key to achieve the transition toward clean energy system. Among them, the geothermal energy has a production whose effectiveness requires sufficient understanding of the temperature distribution and fluid circulation at depth,

Strike-slip shear zones of the Iberian Massif: Are they coeval? [PDF]

open access: yesLithosphere, 2017
Strike-slip shear zones of the Variscan orogen are used to derive the evolution of paleostrain and discuss the kinematics of the waning stages of the Gondwana-Laurussia collision during the amalgamation of Pangea. In the Iberian Massif, the recognition of three late Carboniferous deformation events related to strike-slip tectonics (D3, D4, D5) in the ...

Half-Century Changes in LULC and Fire in Two Iberian Inner Mountain Areas

open access: yesFire, 2019
Wildfires in the Iberian Peninsula were large and frequent in the second half of the 20th century. Land use and land cover (LULC) also changed greatly.

The Appinite-Migmatite Complex of Sanabria, NW Iberian Massif, Spain [PDF]

open access: yesJournal of Petrology, 2003
The Sanabria appinitic rocks and host migmatites form an unusual, non-peri-batholithic complex in which all the typical members of the appinite suite are present. It differs from most appinitic complexes in the deeper level of emplacement and the close temporal and spatial association with migmatites.

Glaciers Landscapes during the Pleistocene in Trevinca Massif (Northwest Iberian Peninsula)

open access: yesLand, 2023
The Trevinca Massif is in the northwestern Iberian Peninsula, on the border between Galicia and Castilla-León. Its highest elevation is 2124 m at the Trevinca peak.
