A short guide for the study of anisotropy of magnetic susceptibility (ams) in deformed rocks

The analysis of the Anisotropy of Magnetic Susceptibility (AMS) constitutes a fast and non- destructive technique that has gained the acceptance of structural geologists because it provides valuable information related to the orientation and intensity of the strain ellipsoid of deformed rocks. Part of its strength results from the possibility of (i) characterizing very subtle rock deformation, and (ii) integrating a large number of data, widespread across large areas. Since the pioneer works in the 1950s, a considerable amount of papers applying this technique to a wide variety of issues in Earth Sciences and to almost all rock types (considering both age and lithology) has been published. Here we explore and expose the use of this valuable technique in modern structural geology and tectonics, as well as its benefits and limits.
