Resumen:
Puna is a very large geographical and morpho-structural district located in NW Argentina. This region is characterized by an extremely arid climate, and a very low population density, one ofthe least inhabited areas in the world. It represents a giganticplateau in the Central Andes between 22° 30´ and 25° 30´ S latitude.This high elevated meseta has remained stable and invariableacross very long geological periods. There are deflation surfacesmainly composed by very dry lands with large terrains coveredby clear volcanic sediments and ignimbrites, and lightcoloredhalides and borates deposits found in dry salt lakes.Potential three new astrobleme sites have been detected in the Puna by remote sensors: Salar del Rincón, Salar del Hombre Muerto and Salar de Antofalla.
