The Argentine Basin is a region of the Atlantic Ocean floor off the east coast of Argentina, between the Mid-Atlantic Ridge to the east and the Scotia Basin to the west. To the north is the Brazil Basin, with the two basins being separated by the Rio Grande Rise. The southern edge of the Argentine Basin is formed by the Falklands/Malvinas ...
Salta Basin or Salta Rift Basin is a sedimentary basin located in the Argentine Northwest. [1] [2] The basin started to accumulate sediments in the Early Cretaceous and at present it has sedimentary deposits reaching thicknesses of 5,000 metres (16,000 ft). The basin contains seven sub-basins: Tres Cruces, Lomas de Olmedo, Metán, Alemanía ...
A map of Argentina's river drainage basins. This list is arranged by drainage basin , with respective tributaries indented under each larger stream's name. Rivers in the table above are in bold.
Argentina is home to at least three major endorheic basins or closed water drainage basins e.g. water does not flow to the ocean. Both the northwest and southwest pampas basins in the dry pampas areas of Argentina and the Meseta Somuncura in the Patagonia region of Argentina are endorheic basins. Notable river basins under this classification ...
A map of the endorheic river basins that characterize the altiplano. In the north is Lake Titicaca and the Desaguadero River system; in the south is the Salar de Uyuni salt flat. The non-endorheic altiplano extends southward into Argentina and Chile.
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]
The Neuquén Basin is an important oil and gas producing basin in Argentina. Production started in 1918 and accumulated to 928 thousand cubic metres (5.84 million barrels) of oil equivalent in 2004, representing 45% of the oil production in Argentina and 61% of its gas production. [ 40 ]
As the breakup of Gondwana began, narrow half-grabens filled with volcaniclastic rocks and the Pampa de Agnia Basin formed along the Gastre fault system. The Magallenes Basin experienced rifting and the Chon Aike province witnessed intraplate volcanism during the acceleration of the breakup around 180 to 165 million years ago, as the Weddell ...
