The Magallanes Basin or Austral Basin is a major sedimentary basin in southern Patagonia. The basin covers a surface of about 170.000–200.000 km2 and has a NNW-SSE oriented shape.[1][2] The basin bounds to the west with the Andes mountains and is separated from the Malvinas Basin to the east by the Río Chico-Dungeness High.[1] The basin evolved from being an extensional back-arc basin in the Mesozoic to being a compressional foreland basin in the Cenozoic.[3] Rocks within it derive from the Jurassic Period and includes the Cerro Toro formation.[4]
