(orcid)0000-0002-0504-2352 Petrophysical Characterization of Non-Magnetic Granites; Density and Magnetic Susceptibility Relationships 2022 Access copy available to the general public Unrestricted In this work we establish reliable correlations between density and magnetic susceptibility in three paramagnetic granites from the Pyrenees. In total, 128 sites (310 density measurements and >2600 susceptibility ones) were studied in the Mont Louis-Andorra, Maladeta and Marimanha granitic plutons covering the main range of variability of magnetic susceptibility. Regressions were calculated for every granitic body and an integrated linear function was obtained for the entire dataset: \u03c1 (kgm3) = 2566 (kgm3) + 0.541\u03ba (10\u22126 S.I.) (R:0.97). This relationship is only valid in the paramagnetic domain, where iron is mostly fractioned in iron-bearing phyllosilicates and the occurrence of magnetite is negligible (or at least its contribution to the bulk susceptibility). This relationship, likely different in other bodies, allows for transforming magnetic susceptibility data into density data, helping to constrain gravity modelling when density data from rock samples are scarce. Given the large amount of AMS studies worldwide, together with the quickness and cost-effectiveness of susceptibility measurements with portable devices, this methodology allows for densifying and homogenizing the petrophysical data when modelling granite rock volumes based on both magnetic and gravimetric signals. info:eu-repo/grantAgreement/EC/H2020/731166/EU/Establishing the European Geological Surveys Research Area to deliver a Geological Service for Europe/GeoERA This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 731166-GeoERA info:eu-repo/grantAgreement/ES/MCIU/CGL2017-84901-C2-2-P info:eu-repo/grantAgreement/ES/MICINN/FJC-2019-041058-I info:eu-repo/grantAgreement/ES/MICINN/PID2020-104693GB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2020-114273GB-C22 info:eu-repo/grantAgreement/ES/MICINN/PTA2017-14779-I info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 0.66 2022 Earth and Planetary Sciences (miscellaneous) 2022 Q2 5.2 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Román-Berdiel, Teresa Universidad de Zaragoza (orcid)0000-0002-9743-8695 Calvín, Pablo (orcid)0000-0002-4485-2139 Bouchez, Jean Luc Beamud, Elisabet Ayala, Conxi Loi, Francesca Soto, Ruth (orcid)0000-0002-1929-8850 Clariana, Pilar Margalef, Aina Bach, Nuria Schamuells, Nia Rubio, Félix M.
