Transition from extensional to compressional magnetic fabrics in the Cretaceous Cabuérniga basin (North Spain)

► Transition of extensional to compressional magnetic fabrics in an inverted sedimentary basin. ► Progressive transition of extensional structures to compression-related cleavage is seen. ► Palaeostress analysis from syn-sedimentary faults better constrains the extensional episode. ► Extensional magnetic fabrics are found when there is a certain distance to the cleavage front. ► Methodology applicable to the study of the conditions of tectonic inversion of other basins.
