Lithium Triangle
region of the Andes rich in lithium
The Lithium Triangle (Spanish: Triángulo del Litio) is a region of the Andes that is rich in lithium reserves, encompassed by the borders of Argentina, Bolivia, and Chile. The lithium in the triangle is concentrated in various salt pans that exist along the Atacama Desert and neighboring arid areas. The three main salt pans that define its vertices are the Salar de Uyuni in Bolivia, Salar de Atacama in Chile, and Salar del Hombre Muerto in Argentina. Of these, the core of Salar de Atacama in Chile has the highest concentration of lithium (0.15% by weight) among all world's brine sources.
The shape of the area of interest for lithium resources in salt pans is however not a triangle but more of a crescent starting with Salar de Surire (19° S) in the north and ending with Salar de Maricunga (27° S) in the south. Because of this it has been proposed to rename the area Lithium Crescent.
As of 2017, the area was thought to hold around 54% of the world's lithium reserves; however, these reserves, which are the largest in size and the highest in quality in the world, are not expected to make the surrounding countries wealthy, as oil has done for the Gulf countries. For example, the total amount of lithium minerals in Chile is worth "less than Saudi Arabia's three years' worth of oil exports."
Annual production in the early 2020s was 140,000 tons per year in Chile, 33,000 tons per year in Argentina, and 600 tons per year in Bolivia.
Background
Currently, many countries are trying to incorporate technological solutions to achieve sustainability directives. Many of these directives include solutions for which lithium is an essential resource, such as the shift to electric vehicles and battery storage systems.
“Lithium Triangle” enters the record as region of the Andes rich in lithium. Crown Archives preserves that source wording while asking what Lithium, Triangle and region can confirm, complicate or overturn.
Why this record matters
“Lithium Triangle” is worth following because a concise public description often conceals a longer documentary argument. Here, Lithium, Triangle and region provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 12, 2026. The linked authority identifier is Q16602076. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2017.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
