Salta Basin

Summary

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 (Neocomian) 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, Salfity, El Rey, Sey and Brealito. The basin environment has variously been described as a "foreland rift" and an "intra-continental rift". The basin developed under conditions of extensional tectonics and rift-associated volcanism.[1]

Description edit

The basin basement is composed of rocks belonging to the Puncoviscana Formation.[2] The volcanism that began in the Late Jurassic was initially of subalkaline character (low sodium and potassium content), but turned increasingly alkaline in the Early Cretaceous.[1]

The rifts of Salta Basin developed in a time of generalized extensional tectonics along western South America.[3] It has been proposed that the Salar de Atacama depression in Chile was once a westward rift arm of the Salta Basin.[4]
