Ancochea Soto, Eumenio ; Casquet, César ; Huertas Coronel, María José ; Villaseca González, Carlos | Sociedad Geológica de España | 2002-11During fifty five years professor José María Fúster Casas (7923-2000) works in (Central) Complutense University of Madrid in Igneous and Metamorphic Petrology. He collaborates actively in introducing new petrological techniques as optical micros[...]texto impreso
This study describes rare albitites associated with highly fractionated I-type granitic melts, showing a mineral paragenesis that resembles those of high-temperature metasomatized rocks (fenites) associated with alkaline and carbonatitic intrusi[...]texto impreso
Barbero González, Luis C. ; Glasmacher, U. A. ; Villaseca González, Carlos ; López García, José Ángel ; Martín Romera, Cristina | Springer Science Business Media | 2005Abstract In the Montes de Toledo area, located in the axial part of the Central Hercynian zone, a long-term thermo-tectonic evolution can be deduced from apatite fission-track (AFT) data in conjunction with tight geological constraints derived f[...]texto impreso
The alkaline monzo-syenitic porphyries from the Spanish Central System (SCS) show a heterogeneous composition ranging from basic to acid terms which give rise to major and trace element compositional trends in accordance with fractional crystall[...]texto impreso

Pérez-Soba Aguilar, Cecilia ; Villaseca González, Carlos ; Fernández, Alfredo | Mineralogical Society of America | 2017-04Three Mn-Fe-rich fluorapatite types have been found in the highly evolved peraluminous and perphosphorous granites of the Belvís pluton. One of these apatite types includes abundant graphite microinclusions, suggestive of a magmatic origin for t[...]texto impreso
Villaseca González, Carlos ; Orejana García, David ; Pin, Christian ; López García, José Ángel ; Andonaegui Moreno, Pilar | Elsevier Science B.V., Amsterdam | 2004Les manifestations du magmatisme basique dans le Système central espagnol s’étalent de façon sporadique sur une période de 140 Ma. Les données géochimiques suggèrent des sources mantelliques variables pour les cinq suites magmatiques reconnues. [...]texto impreso
Villaseca González, Carlos ; Ruíz Martínez, Vicente Carlos ; Pérez-Soba Aguilar, Cecilia | Universidad de Barcelona | 2017-12Magnetic susceptibility (MS) has been measured in Variscan granites from central Spain. They yield values in the order of 15 to 180 mu SI units for S-and I-type granites, indicating that both types belong to the ilmenite series. Only samples fro[...]texto impreso
Villaseca González, Carlos ; Huertas Coronel, María José | Seminario de Estudos Galegos. Area de Xeoloxía e Minería ; Instituto Universitario de Xeoloxía "Isidro Parga Pondal" | 1987Se aborda de manera teórica los principales procesos operativos de diferenciación ígnea en secciones transversales de los conductos filonianos, aplicándolo a los diques de pórfido granítico s. 1. del Sistema Central Español. Para estos magmas se[...]texto impreso
Villaseca González, Carlos ; Martín Romera, Cristina ; Barbero González, Luis C. | Elsevier Sciences Ltd. | 2001Granulite terranes from Central Spain are Hercynian anatectic areas of mid-crustal levels (P-T conditions: 750-800 ° C and 4-6 kb), The granulite xenolith suite of the same sector comes from the lower crust as deduced from their P-T estimates (8[...]texto impreso
Villaseca González, Carlos ; Orejana García, David ; Paterson, Bruce A. ; Billstrom, Kjell ; Pérez-Soba Aguilar, Cecilia | E. Schweizerbart'sche Verlagsbuchhandlung | 2007Basic and intermediate meta-igneous xenoliths are very scarce within the granulite population transported by the Permian alkaline lamprophyric dyke swarmof the Spanish Central System(SCS). These xenoliths aremetaluminous pyroxene-bearing charnoc[...]texto impreso
Villaseca González, Carlos ; García Serrano, Javier ; Pérez-Soba Aguilar, Cecilia | Sociedad Española de Mineralogía | 2019-06The Calatrava volcanic field (CVF) comprises about 250 volcanic centers in an area of ~5000 km2. Detailed studies on mantle xenolith suites have been focused on the Cerro Pelado (Villaseca et al., 2010, and referencestherein) and the El Aprisco [...]texto impreso

Orejana García, David ; Losantos, E. ; Villaseca González, Carlos ; Jeffries, T.E. | Universidad Complutense de Madrid | 2015Major and trace element chemistry has been determined in the main minerals (olivine, orthopyroxene, clinopyroxene, plagioclase, amphibole, phlogopite) from the Talavera and La Solanilla gabbroic intrusions (Spanish Central System). The results s[...]
