To establish a comparison with the petrofabric of rocks, AMS was complemented with observations and orientation analyses at the outcrop scale, in oriented polished blocks and in thin sections under the microscope. High resolution sampling (620 specimens from 56 sites located in five transects along a sequence 150 m thick) allowed to characterize the volcaniclastic and lava flow series. The AMS results show a fairly constant average magnetic lineation oriented WNW-ESE (in situ and tilt-corrected) and two secondary maxima (N-S to NE-SW in some areas). The magnetic mineralogy analyses indicate the contribution of paramagnetic and ferromagnetic (magnetite, Tc 580 °C) phases to susceptibility. The magnetic fabric has a close relationship with the spatial distribution and orientation of the mineral and grain components of the studied rocks, mainly controlled by depositional processes, with a negligible contribution of the tectonic imprint. Therefore, the magnetic lineation (i.e. K1 axes) can be reliably used as a paleoflow indicator. Nevertheless, it was not possible to establish a clear correspondence between lithological and magnetic fabric types. The results obtained indicate that the AMS approach represents a powerful tool to infer the paleoflow pattern in ancient volcanic and volcaniclastic rocks, even under a priori unfavourable conditions. 000110621 536__ $$9info:eu-repo/grantAgreement/ES/MCIU/CGL2017-84901-C2-2-P$$9info:eu-repo/grantAgreement/ES/MCIU/FPU19-02353$$9info:eu-repo/grantAgreement/ES/MCIN/AEI/10.13039/501100011033$$9info:eu-repo/grantAgreement/ES/MICINN/PID2020-108753GB-C22$$9info:eu-repo/grantAgreement/ES/MICINN/PID2020-114273GB-C22 000110621 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000110621 590__ $$a2.9$$b2022 000110621 592__ $$a1.107$$b2022 000110621 591__ $$aGEOSCIENCES, MULTIDISCIPLINARY$$b88 / 202 = 0.436$$c2022$$dQ2$$eT2 000110621 593__ $$aGeophysics$$c2022$$dQ1 000110621 593__ $$aGeochemistry and Petrology$$c2022$$dQ1 000110621 594__ $$a6.2$$b2022 000110621 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000110621 700__ $$0(orcid)0000-0003-3652-3527$$aCasas-Sainz, Antonio$$uUniversidad de Zaragoza 000110621 700__ $$aSoto, Ruth 000110621 700__ $$0(orcid)0000-0002-3276-5871$$aGisbert Aguilar, Josep$$uUniversidad de Zaragoza 000110621 700__ $$0(orcid)0000-0002-9743-8695$$aRomán-Berdiel, Teresa$$uUniversidad de Zaragoza 000110621 700__ $$aOliva-Urcia, Belén 000110621 700__ $$aPueyo, Emilio L. 000110621 700__ $$aBeamud, Elisabeth 000110621 7102_ $$12000$$2685$$aUniversidad de Zaragoza$$bDpto.
