The origin and distribution of salts on alluvial fans in the Atacama Desert, northern Chile

Auteur(s) et Affiliation(s)



Description :
As part of an investigation into the relationship of salts and surface weathering features, the aim of this study was to determine the nature, quantity and distribution of salt minerals on the surface of 3 alluvial fans in salar basins representing a transect of different environments in the Atacama Desert, such that the origin and distribution processes of the salts might be inferred. The pattern of salts that might be expected on each fan is first considered by examining regional sources and processes of salt input onto the fans. The observed distribution of salts is subsequently discussed for each fan in a regional comparison.
