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 ...
The Colorado Basin (Spanish: Cuenca del Colorado) is a sedimentary basin located in northeastern Patagonia.The basin stretches across an area of approximately 180,000 square kilometres (69,000 sq mi), of which 37,000 square kilometres (14,000 sq mi) onshore in the southern Buenos Aires Province and the easternmost Río Negro Province extending offshore in the South Atlantic Ocean.

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 ...
The Río Mayer Formation is sequence of sedimentary rocks of Early Cretaceous age that form part of the northern Magallanes Basin (Austral Basin) in Santa Cruz Province, Argentina. It is a lateral equivalent of the Zapata Formation, as described in Chile further south within the same basin. [1]
