The Malvinas Basin (Spanish: Cuenca de Malvinas) is a major sedimentary basin in the Argentine Shelf offshore southern Patagonia. The basin borders to the west with the Río Chico-Dungeness High that separates it from the Magallanes Basin.[1] The southern boundary is formed by the Scotia plate boundary.[2] Contrary to the neighbouring North Falkland and Magallanes Basins, the Malvinas Basin is not known to have commercial hydrocarbon reserves.[3]
