Atacama salt flat

A recent study at the University of Chile found that Atacama salt flat is sinking due to lithium brine extraction.

About Atacma Salt Flat:

• The Atacama Salt Flat (Salar de Atacama) is a large salt flat located in the Atacama Desert in northern Chile.
• It is situated in the Antofagasta Region of northern Chile, near the Andes Mountains.
• It spans an area of approximately 3,000 square kilometers, making it the largest salt flat in Chile and one of the largest in the world.
• Despite the harsh conditions, the Atacama Salt Flat is home to unique ecosystems, including several species of flamingos that feed on microorganisms in the salt lakes.
• The Laguna Chaxa, located within the salt flat, is a popular spot for observing flamingos and other wildlife.
• The Atacama Salt Flat is one of the world’s richest sources of lithium, a key component in batteries for electronics and electric vehicles.
• The brine beneath the surface of the salt flat contains high concentrations of lithium, which is extracted and processed for industrial use.

Geological Formation:

• The extreme aridity and high altitude contribute to the unique conditions of the salt flat, with stark, lunar-like landscapes.
• The salt flat was formed over millions of years through the accumulation of salts and minerals, which were carried by rivers and streams into a basin with no outlet.
• The intense evaporation in this arid region led to the concentration of salts, creating the flat’s characteristic surface.
• The Atacama Desert is one of the driest places on Earth, with some areas receiving less than 1 millimeter of rainfall annually.
