Salt pan at Lake Karum in Ethiopia. Natural salt pans or salt flats are flat expanses of ground covered with salt and other minerals, usually shining white under the sun. They are found in deserts and are natural formations (unlike salt evaporation ponds, which are artificial). A salt pan forms by evaporation of a water pool, such as a lake or ...
The topography of the core portion of the salar exhibits a high level of roughness, the result of evaporation and ephemeral surface water, [9] unlike the most other salt flats, as for example the Salar de Uyuni, which is periodically covered with shallow water. Some areas of the salt flat form part of Los Flamencos National Reserve. The Laguna ...
Salta Basin or Salta Rift Basin is a sedimentary basin located in the Argentine Northwest. [1] [2] The basin started to accumulate sediments in the Early Cretaceous and at present it has sedimentary deposits reaching thicknesses of 5,000 metres (16,000 ft). The basin contains seven sub-basins: Tres Cruces, Lomas de Olmedo, Metán, Alemanía ...

The nearest salt flats are the ones of Antofalla, Hombre Muerto (both in the north of Catamarca Province), Pocitos (in the east) and the Salinas Grandes of Jujuy and Salta provinces. The Salar de Arizaro is crossed in the middle by the Salta–Antofagasta railway and the Provincial Route 27 [1] (part of the former RN 59).
Some environmentalists say Eramet's project is the latest threat to previously untouched salt flats. "They are a perfect system of equilibrium, of life," said Mara Puntano, an activist in Salta ...
An open water body covers 65 square kilometres (25 sq mi) in the eastern part. [11] Close to Salar del Hombre Muerto lie ten potential impact craters with diameters of 90–250 metres (300–820 ft) that may have formed during the last 500,000 years [ 12 ] and certainly very recently, although they could also be collapse structures in the ...
Chile's Atacama salt flat is sinking at a rate of 1 to 2 centimeters (0.4 to 0.8 inches) per year due to lithium brine extraction, according to a study by the University of Chile. The study used ...
