U-Pb-age from undeformed granite pebbles in Carboniferous Culm conglomerates: new geochronological constrains on the Variscan events in the Pyrenees

U-Pb ages of zircon and apatite in undeformed granite pebbles of synorogenic Carboniferous Culm conglomerates confirm the existence of an early Carboniferous (Visean to Bashkirian) magmatic event in the core of the Pyrenees. In this so-called Axial Zone, early Carboniferous magmatism developed in at...
