These saline crusts were gradually deposited during the eastward tilting of the tectonic block that supports the Niger River; (2) the irrigation processes during the recent reflooding of the Fala of Molodo (river diversion in 1950). These used very poorly mineralized surface water but reintroduced into the alluvial groundwater system – generally of a low permeability (K=10–6 m s–1) – salts derived from the ancient solonchaks; and (3) the redeposition of the dissolved salts on the surface due to the intense evapotranspiration linked to the present Sahelian climate.

On the basis of data analysis on various scales, it is concluded that the current extent of the surface saline soils is due to a combination of three factors: (1) the existence of ancient saline soils (solonchaks) resulting from the creation of a broad sabkha west of the former course of the Niger River, now called the Fala of Molodo.

Due to its large size, flat surface and high albedo with a thin layer of water, and minimal deviation of altitude, the Uyuni solonchak is an ideal tool for testing and calibrating remote sensing instruments on orbiting satellites.

The results showed that A. canescens is found mainly in soils of the Calcisols, Solonchaks and Solonets groups and that phosphorus and potassium contents significantly influence the presence of this species.

The dome-shaped and slightly extended hills representing extinct volcanoes conduits are fancifully scattered; between the hills there are solonchaks where table salt was mined.
