Outcrop data for each formation of the Arroyo Atravesado locality of 103 specimens and its anisotropy of magnetic susceptibility parameters. B. Plane: bedding strike (0º-360º) and dip (90° clockwise, from given strike, 0º-90º). Cleavage: direction (0º-360º) and dip (90° clockwise, from given strike, 0º-90º). S<sub>0</sub> and S<sub>1</sub> foliations measured in thin sections (0°-360°). K<i><sub>max</sub></i>: average orientation of the maximum axe of AMS; K<sub>m</sub> = (K<sub>max</sub>+K<sub>int</sub>+K<sub>min</sub>)/3: average susceptibility volume in SI units; P<sub>j</sub> av: average anisotropy degree (P = K<sub>max</sub>/K<sub>min</sub>: anisotropy degree according to <i>Nagata</i>, 1961); T: average shape parameter of Jelinek (<i>Jelinek</i>, 1981); L = K<sub>max</sub>/K<sub>int</sub>: Average li...
