Exposed along the northwest margin of the basin, a salt-cored range, the Cordillera de la Sal, records the Mid-Miocene to recent sedimentological and structural development of this basin. Sediments of the Mid-Miocene Vilama Formation record the complex interaction between regional/local climate change, halokinesis and compressional deformation. This study reveals how these factors have controlled the facies development and distribution within the Salar de Atacama.
