Kinematic interpretation of the Cañamares shear zone (central Iberian zone, Iberian Massif): from late Variscan strike-slip tectonics to Alpine deformation

Journal of Structural Geology
The Cañamares shear zone is located at the eastern end of the Spanish-Portuguese Central System, in the Central Iberian Zone of the Iberian Massif. It is a dextral transpressive structure, generated during the third Variscan deformation stage (D3: 318 ...

The late-Variscan peraluminous Valdepeñas pluton (southern Central Iberian Zone) [PDF]

Geologica Acta, 2017
The Valdepeñas pluton is the easternmost outcrop of the Cáceres-Valdepeñas magmatic alignment (southern Central Iberian Zone). This massif is constituted by a cordierite-bearing porphyritic monzogranite and may be grouped within the so-called “Serie ...

Geology and mineralogy of Li-mineralization in the Central Iberian Zone (Spain and Portugal) [PDF]

Mineralogical Magazine, 2016
Lithium (Li) mineralization is common in the Central Iberian Zone and, to a lesser extent, in the Galizia-Trás-Os-Montes Zone of Spain and Portugal, occurring along a c. 500 km-long NNW-SSE striking belt.

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)

Minerals (Basel, Switzerland), 2022
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 Variscan granites, pegmatites and ...

Late Ediacaran carbonate production and REE+Y signatures tracing redox conditions in a Cadomian retroarc basin, Central Iberian Zone, Spain [PDF]

Geologica Acta
The late Ediacaran carbonate production recorded in a Cadomian retroarc basin from the Iberian Peninsula provides an excellent opportunity to evaluate the tectonic and redox factors that controlled the infill of the foredeep troughs, located between ...
