Space and time in the tectonic evolution of the northwestern Iberian Massif: Implications for the Variscan belt [PDF]

, 2007
Recent advances in geochemical studies of igneous rocks, isotopic age data for magmatism and metamorphism, quantitative pressure-temperature (P-T) estimates of metamorphic evolution, and structural geology in the northwestern Iberian Massif are integrated into a synthesis of the tectonic evolution that places the autochthonous and allochthonous ...

Glacial geomorphology of the High Gredos Massif: Gredos and Pinar valleys (Iberian Central System, Spain)

Journal of Maps, 2020
We present a detailed geomorphological map of the landform assemblages originated by the two major paleoglaciers of the Sierra de Gredos mountain range in the Spanish Iberian Central System. Based on previous works, our map focused on the features formed

Ediacaran ophiolites from the SW Iberian Massif

[ES] El basamento cadomiense del SW del Macizo Ibérico contiene varias unidades máficas – ultramáficas de naturaleza ofiolítica. La Ofiolita de Calzadilla y la Ofiolita de Mérida tienen protolitos formados a c. 602 Ma y 594 Ma, respectivamente. La composición de sus rocas máficas permiten interpretarlas como ofiolitas de zona de supra-subducción ...

A revised Ordovician age for the Sisargas orthogneiss, Galicia (Spain). Zircon U-Pb ion-microprobe and LA-ICPMS dating

Geologica Acta, 2009
The Sisargas orthogneiss is located in the Schistose Domain of the Galicia Trás-Os-Montes Zone. It has previously been dated by Allegret and Iglesias (1987) who reported an U-Pb upper intercept at 570 ± 14 Ma, considered to be the crystallization age ...
