From Wikipedia, the free encyclopedia
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
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.
