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). S0 and S1 foliations measured in thin sections (0°-360°). Kmax: average orientation of the maximum axe of AMS; Km = (Kmax+Kint+Kmin)/3: average susceptibility volume in SI units; Pj av: average anisotropy degree (P = Kmax/Kmin: anisotropy degree according to Nagata, 1961); T: average shape parameter of Jelinek (Jelinek, 1981); L = Kmax/Kint: Average lineation; F = Kint/Kmin: Average foliation (Flinn, 1962).
