In this work, we test the analysis of anisotropy of magnetic susceptibility (AMS) for the study of diapirs in the Naval salt wall that is located in the western end of the South Pyrenean Central Unit. Two hundred eighty-six specimens from 30 sites were sampled in the mobilized Middle-Upper Triassic evaporites and shales that constitute the core of this diapir. Resulting magnetic ellipsoids are …
