Layout

The area of each map is inscribed within the divide of its own drainage basin. 

The optimal printing scale is 1:100,000, expandable to 1:50,000.

Each map includes all the stratigraphic units cropping out in the area, and its structures. 

Likewise, the entire drainage network -permanent and temporary streams- has been designed at a detailed scale, an optimal tool for geomorphological, geochemical and hydrological studies, useful for lithium and potassium prospecting. 

The maps record the geomorphological units that originated the Quaternary deposits: alluvial fan, mudflow, lava flow, alluvial cone (functional and terraced), detritus cone, detritus slope, glacis (functional and terraced), sublacustrine delta, lacustrine flow, cordoned dune, fixed dune, semilunar dune, drifting sand cover, deflation bucket, nebka, in addition to fluvial-runoff strike, lacustrine-shore line, springs and lagoons.
