10 p, 1.9 MB U-Pb zircon SHRIMP evidence for Cambrian volcanism in the Schistose Domain within the Galicia-Trás-os-Montes Zone (Variscan Orogen, NW Iberian Peninsula) / Farias Arquer, Pedro (Universidad de Oviedo. Departamento de Geología) ; Ordoñez-Casado, B. (Universidad de Oviedo. Departamento de Geología) ; Marcos, A. (Universidad de Oviedo. Departamento de Geología) ; Rubio-Ordoñez, A. (Universidad de Oviedo. Departamento de Geología) ; Fanning, C. M. (Australian National University. Research School of Earth Sciences)
SHRIMP U-Pb zircon analyses have shown the complexity of dating volcanic rocks due to the presence of inner cores within zircon crystals. Using the cathodoluminescence studies assisting ion microprobe analyses allow as to conclude that: the two low-grade metavolcanic samples from the Schistose Domain of the Galicia-Trás-os-Montes Zone in the northeast limb of the Verín-Bragança synform (NW Spain and NE Portugal) yield ages of 488.

The northern termination of the Schistose Domain of the Galicia-Trás-os-Montes Zone is a tectonic slice named the Rio Baio Thrust Sheet, which is sandwiched between the Cabo Ortegal Complex and the Ollo de Sapo Domain of the Central-Iberian Zone. [...]
