Origin of cordierite-bearing monzogranites from the southern Central Iberian Zone – Inferences from the zoned Sierra Bermeja Pluton (Extremadura, Spain)

Lithos, 2019
Voluminous peraluminous (biotite, biotite–cordierite and cordierite–muscovite-bearing) granitic plutons were emplaced in the southern part of the Central Iberian Zone (Iberian Massif) during the waning stages of the Variscan Orogeny.

PETROLOGY AND GEOCHEMISTRY OF THE FELSIC HYPABYSSAL MAGMATISM IN NORTHERN PORTUGAL (CENTRAL IBERIAN ZONE)

SGEM International Multidisciplinary Scientific GeoConference� EXPO Proceedings, 2023
In the Central Iberian Zone, multiple subvolcanic intrusions were emplaced during the final stages of the Variscan orogeny. The felsic component of this magmatic episode is mainly represented by dykes and masses of granite porphyries and microgranites ...

Geochemistry, geochronology and mineralisation potential of the granites in the Central Iberian Zone: The Jalama batholith [PDF]

Chemie Der Erde, 2008
The Jalama batholith (Spain and Portugal) is one of the numerous granites ofthe Central Iberian Zone with Sn- and W-associated mineralisation. On the basis of petrographical and geochemical characterisation three types of granite have been distinguished: inhomogeneous granitoids, porphyrytic granites and leucogranites, all of these being

Caradoc through Early AshgillBrachiopods from the Central-Iberian zone (Central Spain)

Geobios, 1995
Abstract Caradoc through early Ashgill brachiopods from the Central-Iberian Zone, representing the latest cold water brachiopodassociations of the West European Platform developed on the North-African Gondwana margin, have been studied. Twenty one brachiopod taxa, including two new species ( Tafilaltia brevimusculosa and Hedstroemina almadenensis ),

U-Pb age constraints on the protolith, cooling and exhumation of a Variscan middle crust migmatite complex from the Central Iberian Zone: insights into the Variscan metamorphic evolution and Ediacaran paleogeographic implications

Journal of the Geological Society, 2022
The Figueira de Castelo Rodrigo – Lumbrales Anatectic Complex (FCR-LAC) located in the Central Iberian Zone of the European Variscan Belt is delimited by two shear zones, which have been interpreted as constraining its exhumation.

The structure of a major suture zone in the SW Iberian Massif: the Ossa-Morena/Central Iberian contact

Tectonophysics, 2001
Abstract We have investigated the stratigraphy, structure and metamorphism of the boundary between the Ossa Morena Zone (OMZ) and the Central Iberian Zone (CIZ), two significant continental portions of the Variscan Iberian Massif. The OMZ/CIZ contact is marked by a strongly deformed and metamorphosed NW–SE trending narrow band, namely, the Central ...
