A revised Ordovician age for the Miranda do Douro orthogneiss, Portugal. Zircon U-Pb ion-microprobe and LA-ICPMS dating
The Miranda do Douro orthogneiss was believed to be the oldest magmatic rock of the Central Iberian Zone, onthe base of a U-Pb discordia upper intercept of 618 ± 9 Ma. Nevertheless, new ion-microprobe and LA-ICPMSU-Pb zircon dating revealed that the crystallization age was 483 ± 3 Ma. The orthogneis...
