“…This result suggests that the magnetization of the upper Carapacha in this region is also post-folding at 99% level of confidence (McFadden, 1990). The direction-correction tilt test (Enkin, 2003) yields a negative fold test with an optimal untilting at -12.3±25.1% (Fig. 7b).…”

Paleomagnetic results from Permian clastic and igneous rocks of the Carapacha Basin of the Gondwáides orogenic zone of central Argentina are mainly consistent with results reported previously from the same zone further east, e.g., in the Sierra de la Ventana. Three lithologic entities were analysed: the lower member and upper member of the Carapacha Formation, and an andesite intrusive into the upper member. The directions of their characteristic remanences are similar, differ significantly from the present field direction, and are post-folding. The in situ magnetization directions are moreover consistent with directions expected for late Permian poles of the APWP for South America. The in situ pole for the lower Carapacha Formation is 70• S, 049• E, A95=11• (San Roberto pole); the pole for the upper Carapacha, combined with similar directions from the intrusive, is 64• S, 005• E, A95=5• (Río Curacó pole). These magnetizations imply that the Carapacha Formation, with a minimum age of early Late Permian (about 260 Ma.), was deformed before the end of the Permian. Structural evidence, as well as paleomagnetic, IRM, and AMS experimental results, support the interpretations. The paleogeographic implications of these results are interpreted as a significant counterclockwise movement of Gondwana between the early and the late Permian.

“…The statistical significance of the fold test is mature (e.g. Tauxe & Watson 1994;McFadden 1998;Enkin 2003), but mathematical approaches to the fold test do not consider phenomena such as folding kinematics. While some authors have already considered this problem (Cairanne et al 2002;Delaunay et al 2002;Waldhör & Appel 2006;Villalaín et al 2015), further advances in this regard need to be accomplished.…”
