Posets pluton: a geochronological piece in the puzzle of the Axial Zone of the Pyrenees

Abstract A detailed geochronological study was conducted on zircons from a diorite sample of the Posets pluton (Axial Zone, Pyrenees). The extracted igneous constrain emplacement to 302 ± 2 Ma and 301 3 Ma, by means U–Pb sensitive high-resolution ion microprobe (SHRIMP) laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analyses, respectively. Considering syn- late-tectonic during main Variscan deformation event (D ), obtained ages long-lasting D , associated with dextral transpression registered through Axial Zone Pyrenees.
