Direct measurement of magnetic susceptibility in facies and detailed grids of magnetometry, electromagnetic multifrequency and ground-penetrating radar (50e500 MHz antennas) have been performed in two study areas where the upper Kimmeridgian rocks are nearly horizontal. Magnetometry indicates negative anomalies in residual magnetic field and vertical magnetic gradient related to reef pinnacles and faults. Electromagnetic data reveal that positive anomalies of apparent conductivity correlate with non-reefal facies. The areal distribution of magnetometry and EM data does not permit the unequivocal identification of pinnacles and faults at the studied area. By contrast, ground penetrating radar profiles and maps of relative reflectivity in two way travel time slices are useful for the identifi- cation of faults (hyperbolic anomalies) and reefal and non-reefal facies (radar facies A and B, respec- tively). The integration of geophysical data, mainly ground penetrating radar, has permitted the 3D reconstruction of reef pinnacles and its tectonic framework. info:eu-repo/grantAgreement/ES/MINECO/CGL2014-53548 info:eu-repo/grantAgreement/ES/UZ/E27 info:eu-repo/grantAgreement/ES/UZ/IUCA-H54 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.888 2016 GEOSCIENCES, MULTIDISCIPLINARY 43 / 188 = 0.229 2016 Q1 T1 1.597 2016 Economic Geology 2016 Q1 Geology 2016 Q1 Stratigraphy 2016 Q1 Oceanography 2016 Q1 Geophysics 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion San Miguel, Galo (orcid)0000-0003-1112-524X Bádenas, Beatriz Universidad de Zaragoza (orcid)0000-0002-2430-7424 Aurell, Marcos Universidad de Zaragoza 2000 428 Universidad de Zaragoza Dpto.
