Margalef, A. ; Casas Tuset, Josep María ; Castiñeiras García, Pedro ; Navidad Fernández de la Cruz, Marina ; Liesa, M. | Sociedad Geológica de España. | 2016The first LA-ICP-MS U-Pb detrital zircon ages from quartzites located in the Ordovician rocks from the Central Pyrenees (the Rabassa Dome, Andorra) were investigated. The four studied samples present very similar U-Pb age patterns. The main age [...]texto impreso
Liesa Torre Marín, Montserrat ; Casas Tuset, Josep María ; Castiñeiras García, Pedro ; Navidad Fernández de la Cruz, Marina ; Carreras, Jordi | Sociedad Geológica de España. | 2008New geochronological data from pre-Variscan igneous rocks of the Eastern Pyrenees (Canigó, Roc de Frausa and Cap de Creus massifs) confirm the presence of Neoproterozoic series in the Pyrenees, as the Balaig micaschists in the Canigó massif and [...]texto impreso
Margalef, Aina ; Castiñeiras García, Pedro ; Casas Tuset, Josep María ; Navidad Fernández de la Cruz, Marina ; Liesa Torre Marín, Montserrat ; Linnemann, Ulf ; Hofmann, Mandy ; Gärtner, Andreas | Elsevier | 2016-03-16The first LA-ICP-MS U–Pb detrital zircon ages from quartzites located below (three samples) and above (one sample) the Upper Ordovician unconformity in the Central Pyrenees (the Rabassa Dome, Andorra) were investigated. The maximum depositional [...]texto impreso

Navidad Fernández de la Cruz, Marina ; Barnolas Cortina, A. | Instituto Geológico y Minero de España (Madrid) | 1991En el presente trabajo se caracterizan petrológica y geoquímicamente las rocas metavolcánicas del Ordovícico Superior de los Catalánides (Gavarres y Guilleries) y los ortoneises de las Guilleries. Estos últimos se encuentran en disposición estra[...]texto impreso
Navidad Fernández de la Cruz, Marina ; Álvaro, M. | Instituto Geológico y Minero de España (Madrid) | 1985El Triásico Superior de Mallorca presenta un tramo rojo vulcano-sedimentario inferior y un tramo carbonatado superior. En ambos existen coladas volcánicas constituidas por basaltos olivínicos espilitizados de afinidad alcalina. Este magmatismo a[...]texto impreso
Navidad Fernández de la Cruz, Marina ; Castiñeiras García, Pedro ; Casas Tuset, Josep María ; Liesa Torre Marín, Montserrat ; Fernández Suárez, Javier ; Barnolas Cortina, A. ; Carreras, Jordi ; Gil Peña, Inmaculada | Elsevier Science B. V., Amsterdam | 2010This paper presents new geochronological, geochemical and isotopic data for Late Ordovician magmatism (455±2 Ma) from the Variscan massifs in the northeastern Iberian Peninsula. This magmatism is mainly composed of aluminous and metaluminous plu[...]texto impreso
Casas Tuset, Josep María ; Castiñeiras García, Pedro ; Navidad Fernández de la Cruz, Marina ; Liesa Torre Marín, Montserrat ; Carreras, Jordi | Elsevier Science B. V., Amsterdam | 2010New geochronological data from the Canigó massif (Eastern Pyrenees) using U–Pb SIMS on zircon provide evidence of the existence of a Late Ordovician (456–446 Ma) plutonic event that emplaced granitic and dioritic bodies into a Late Neoproterozoi[...]texto impreso
Castiñeiras García, Pedro ; Navidad Fernández de la Cruz, Marina ; Casas Tuset, Josep María ; Liesa Torre Marín, Montserrat ; Carreras, Jordi | University of Chicago Press | 2011Zircon composition (U, Th, rare earth elements, and Hf) was tested as a tracer of petrogenetic processes in a set of metaigneous rocks from two pre-Ordovician massifs in the Pyrenees, Canigo´ and Albera. Two groups were differentiated after anal[...]texto impreso
Casas Tuset, Josep María ; Navidad Fernández de la Cruz, Marina ; Castiñeiras García, Pedro ; Liesa Torre Marín, Montserrat ; Aguilar, Carmen ; Carreras, Jordi ; Hofmann, Mandy ; Gärtner, Andreas ; Linnemann, Ulf | Springer-Verlag | 2015-06Geochronological U–Pb (LA-ICP-MS), geochemical and isotopic data from metavolcanic felsic rocks of the Canigó and Cap de Creus massifs in the Eastern Pyrenees provide evidence of an Ediacaran magmatic event lasting 30 Ma in NE Iberia. These data[...]texto impreso
Liesa Torre Marín, Montserrat ; Carreras, Jordi ; Castiñeiras García, Pedro ; Casas Tuset, Josep María ; Navidad Fernández de la Cruz, Marina ; Vilà i Pranella, Miquel | Instituto de Ciencias de la Tierra "Jaume Almera" (Barcelona) | 2011New geochronological data from the Albera Massif confirm the presence of an Early – Mid Ordovician igneous event (472 - 465Ma) recorded in the pre-Variscan rocks of the Pyrenees. This event resulted in the emplacement of a large granitic body in[...]texto impreso
Castiñeiras García, Pedro ; Navidad Fernández de la Cruz, Marina ; Liesa Torre Marín, Montserrat ; Carreras, Jordi ; Casas Tuset, Josep María | Elsevier B.V. | 2008New geochronological data from low- to medium-grade metamorphic areas of the Eastern Pyrenees (Canigó, Roc de Frausa and Cap de Creus massifs) confirm the presence of two significant pre-Variscan igneous events: Ediacaran–Early Cambrian and Earl[...]texto impreso
Aguilar, Carmen ; Liesa Torre Marín, Montserrat ; Castiñeiras García, Pedro ; Navidad Fernández de la Cruz, Marina | Geological Society of London. | 2014-03Variscan migmatites cropping out in the eastern Pyrenees were dated together with Late Variscan plutonic rocks. Upper Proterozoic–Lower Cambrian series were migmatized during a thermal episode that occurred in the interval 320–315 Ma coeval with[...]
