[Abstract] The age of glacial features subaerial exposition: polished surfaces and morainic blocks using cosmogenic isotopes in granite substrate areas of the NW Iberian Peninsula have permitted to distinguish several glacier phases in which until the moment was considered a single one attributed to the Würm. The resulting data are roughly consistent with the previous geomorphologic model for the area and improves the chronological accuracy and the understanding of the Pleistocene glacial dynamics in the NW Spain. The proposed sequence of events also fits very well with previous palaeoclimate reconstructions for the same period at world scale
