Resumen:
The Ushuaia Pluton (UP) is one of the five isolated intrusive bodies of the Fuegian Batholith (FB) in the Argentine sector of Tierra del Fuego north of the Beagle Channel (Figure 1). These intrusive bodies are located in the southernmost tip of Andean Cordillera where there is an abrupt change of about 90° in its strike around 53°S from a roughly north-south direction in continental Patagonia into an east-west orogen in the island of Tierra del Fuego. This sharp orogene curvature is presently contentious, as it has been considered either as a post Early Cretaceous feature likely related to the opening of the Drake Passage (Dalziel et al., 1974) or that it is due to major strike-slip offsets (Cunningham, 1993).
