This work, with six new zircon laser ablation inductively coupled plasma mass spectrometry ages obtained from some of the most representative outcrops, provides the most complete age repository for the calc-alkaline magmatism of the prolongation of the Cantabrian Zone within the Iberian Chain. The obtained ages range between 294 and 288 Ma (Cisuralian Epoch) and show a well-defined peak at 290 Ma, which can be attributed to a main magmatic activity stage. This result allows us to correlate and integrate this magmatism within the widespread SW European calc-alkaline magmatism province developed under strike-slip tectonics. Therefore, the Iberian Chain magmatism and its age can be considered as a good temporal marker for the upper limit of the compressive tectonics associated with the Variscan Orogeny and the onset of the extensional tectonics linked to Permo-Triassic rifting. 000145052 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E32-17R$$9info:eu-repo/grantAgreement/ES/MICINN/PID2019-108753GB-C22 000145052 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000145052 590__ $$a2.6$$b2023 000145052 591__ $$aGEOSCIENCES, MULTIDISCIPLINARY$$b97 / 254 = 0.382$$c2023$$dQ2$$eT2 000145052 592__ $$a1.166$$b2023 000145052 593__ $$aGeology$$c2023$$dQ1 000145052 594__ $$a6.0$$b2023 000145052 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000145052 700__ $$aEsteban, José Julián 000145052 700__ $$aGalé, Carlos 000145052 700__ $$0(orcid)0000-0001-6110-1081$$aGil-Imaz, Andrés$$uUniversidad de Zaragoza 000145052 700__ $$0(orcid)0000-0002-3609-7380$$aLago, Marceliano 000145052 7102_ $$12000$$2428$$aUniversidad de Zaragoza$$bDpto.
