Magnetic anisotropy reveals Neogene tectonic overprint in highly strained carbonate mylonites from the Morcles nappe, Switzerland

► Separation of paramagnetic and diamagnetic subfabrics in highly deformed carbonates. ► Strong correlation between calcite CPO and strength of the diamagnetic sub fabric. ► Separated subfabrics are linked to Neogene orogen parallel extensional deformation. ► Partial tectonic overprint weakens the overall magnetic anisotropy and texture intensity
