The composite Sierra Bermeja Pluton (southern Iberian Massif): science, heritage and geoconservation [PDF]

open access: yesJournal of Maps, 2019
The Sierra Bermeja Pluton (∼60 km2 surface area) exemplifies a type of controversial granites of the Iberian Massif (European Variscan Belt), the cordierite-bearing ‘Serie Mixta’ (mixed series) monzogranites.

Mineral chemistry dataset of the Tournaisian – Lower Viséan submarine basaltic volcanism of the Matachel Basin (SW Iberian Massif). [PDF]

open access: yesData in Brief, 2023
The Matachel Basin is a tectono-stratigraphic unit of Ossa-Morena Zone (southern Iberian Massif) that encompasses an Upper Tournaisian – Viséan basaltic sequence, generated by effusive and explosive eruptions in a shallow submarine setting.

What can seismic noise tell us about the Alpine reactivation of the Iberian Massif? An example in the Iberian Central System [PDF]

open access: yesSolid Earth, 2020
The Iberian Central System, formed after the Alpine reactivation of the Variscan Iberian Massif, features maximum altitudes of 2500 m. It is surrounded by two foreland basins with contrasting elevation: the Duero Basin to the north, located at 750–800 m,

Detrital zircon similarities and dissimilarities between the Iberian Pyrite Belt, Ossa-Morena Zone and Meguma

open access: yesGeologica Acta, 2022
Despite the so-called exotic nature of the South Portuguese Zone relatively to the other major domains of the Iberian Massif of peri-Gondwanan affinity, Devonian detrital rocks of the oldest strata in the Iberian Pyrite Belt have a remarkable resemblance

First report of the mitrate Mitrocystella (Echinodermata, Stylophora) in the Middle Ordovician of the Crozon Peninsula, Brittany (France) [PDF]

open access: yesEstonian Journal of Earth Sciences, 2023
The mid-Ordovician mitrocystitid mitrate Mitrocystella incipiens was one of the most widespread stylophorans in the high latitude Mediterranean Province, with occurrences in the Armorican Massif (France), the Iberian Peninsula (Portugal and Spain) and ...

Evolution of the Iberian Massif as deduced from its crustal thickness and geometry of a mid-crustal (Conrad) discontinuity [PDF]

open access: yesSolid Earth, 2021
Normal incidence seismic data provide the best images of the crust and lithosphere. When properly designed and continuous, these sections greatly contribute to understanding the geometry of orogens and, along with surface geology, unraveling their ...

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

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.

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.
