Resumen:
The tectonic evolution of the Southern Andes in Tierra del Fuego has been the subject of numerous studies in recent years (e.g. Klepeis, 1994, Cunningham, 1995, Mukasa and Dalziel, 1996, Diraison et al., 2000, Lodolo et al., 2003, etc.), but several topics still remain controversial, i.e: the timing and magnitude of an hypothetical oroclinal bending, the competing importance of thrust versus strike-slip tectonics, the role and mechanisms of a back-arc basin inversion, etc. As part of a multidisciplinary study, a reconaissance anisotropy of magnetic susceptibility (AMS) and paleomagnetic survey across the Fuegian Andes in the Argentine sector of the Isla Grande de Tierra del Fuego was carried out. First results from this study are reported here.
