Resumen:
|
New geochronological data from pre-Variscan igneous rocks of the Eastern Pyrenees (Canigó, Roc de Frausa and Cap de Creus massifs) confirm the presence of Neoproterozoic series in the Pyrenees, as the Balaig micaschists in the Canigó massif and the Lower Series in the Roc de Frausa and Cap de Creus massifs. That is, most of the pre-Upper Ordovician sequence in these massifs has to be Late Neoproteozoic in age. These geochronological data allow the correlation of the series along the Eastern Pyrenean massifs. The data also show two different ages (Late Neoproterozoic and Early Ordovician) and significance for the large bodies of granitic orthogneisses intruded at different levels in the series.
