Compositional Variations in Apatite and Petrogenetic Significance: Examples from Peraluminous Granites and Related Pegmatites and Hydrothermal Veins from the Central Iberian Zone (Spain and Portugal)
Roda Robles, María Encarnación ; Gil Crespo, Pedro Pablo ; Pesquera Pérez, Alfonso ; Lima, Alexandre; Garate Olave, Idoia; Merino Martínez, Enrique; Cardoso Fernandes, Joana; Errandonea Martín, Jon (MDPI, 2022-11-01)Apatite can be used as an archive of processes occurring during the evolution of granitic magmas and as a pegmatite exploration tool. With this aim, a detailed compositional study of apatite was performed on different ... -
Low–Ti Continental Tholeiite Origin of Magmas With Calc-Alkaline Signature in Transcurrent Settings: The Mississippian Matachel Volcanic Field (SW Iberian Massif)
Sarrionandia-Ibarra Eguidazu, Fernando; Errandonea Martín, Jon; Larrondo, E.; Carracedo Sánchez, Manuel; Abalos Villaro, Benito; Gil Ibarguchi, José Ignacio (Wiley, 2023-11)In the Mississippian Matachel small volcanic field of the Ossa-Morena Zone (southern Iberian Massif) outpoured basic-intermediate lavas exhibit geochemical characteristics of Low-Ti continental tholeiites and calc-alkaline ... -
Metasomatic effect of Li-bearing aplite-pegmatites on psammitic and pelitic metasediments: Geochemical constraints on critical raw material exploration at the Fregeneda-Almendra Pegmatite Field (Spain and Portugal)
Errandonea Martín, Jon; Garate Olave, Idoia; Roda Robles, María Encarnación ; Cardoso Fernandes, Joana; Lima, Alexandre; dos Anjos Ribeiro, Maria; Teodoro, Ana Claudia (Elsevier, 2022-11)Fluid-assisted mass transfer and re-equilibration of mineral phases are common consequences of metasomatism associated with igneous intrusions. The addition and/or removal of chemical components in these environments may ... -
Mineral chemistry dataset of the Tournaisian – Lower Viséan submarine basaltic volcanism of the Matachel Basin (SW Iberian Massif).
Sarrionandia-Ibarra Eguidazu, Fernando; Errandonea Martín, Jon; Larrondo, E.; Carracedo Sánchez, Manuel; Abalos Villaro, Benito; Gil Ibarguchi, José Ignacio (Elsevier, 2023-02)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 ... -
Petrology of cordierite-bearing monzogranites and related mesocratic rocks from the Sierra Bermeja Pluton (southern Iberian Massif)
Errandonea Martín, Jon (2019-09-20)La Zona Centro Ibérica (Macizo Ibérico) comprende abundantes cuerpos graníticos peralumínicos emplazados durante las etapas tardías del Orógeno Varisco, entre los que se encuentra el plutón de Sierra Bermeja (Extremadura). ... -
The composite Sierra Bermeja Pluton(southern Iberian Massif): science, heritage andgeoconservation
Errandonea Martín, Jon; Sarrionandia-Ibarra Eguidazu, Fernando; Junguitu Iñiguez de Heredia, Yosu; Carracedo Sánchez, Manuel; Eguíluz Alarcón, Luis ; Gil Ibarguchi, José Ignacio (Taylor & Francis, 2019-07-03)The Sierra Bermeja Pluton (similar to 60 km(2) surface area) exemplifies a type of controversial granites of the Iberian Massif (European Variscan Belt), the cordierite-bearing 'Serie Mixta' (mixed series) monzogranites. ... -
The Tres Arroyos Granitic Aplite-Pegmatite Field (Central Iberian Zone, Spain): Petrogenetic Constraints from Evolution of Nb-Ta-Sn Oxides, Whole-Rock Geochemistry and U-Pb Geochronology
Garate Olave, Idoia; Roda Robles, María Encarnación ; Gil Crespo, Pedro Pablo ; Pesquera Pérez, Alfonso ; Errandonea Martín, Jon (MDPI, 2020-11-12)Abundant Li-Cs-Ta aplite-pegmatite dykes were emplaced in the western Central Iberian Zone of the Iberian Massif during the Variscan Orogeny. Their origin and petrogenetic relationships with the widespread granitoids have ...
