The salt flats of the "Lithium Triangle"—the high desert region where Chile, Argentina and Bolivia intersect which is currently home to the most productive lithium sources in the world—and the Dasht-i-Nawar have several uncanny similarities. They are all arid to semi-arid high-altitude salt flats where flamingos like to breed; that's the superficial part. They all sit in high-altitude contact zones between tectonic plates, zones where ancient volcanism left behind mineral-rich igneous rocks. Most important, all three are basins surrounded by old volcanoes. (Shroder says that the Dasht-i-Nawar is what remains of the crater of a stratovolcano that erupted 2.2 million years ago.) Over the millennia, as the ice and snow melts off the surrounding mountains and volcanoes every year and seeps down to the basin below, that water leaches minerals from the volcanic rock it encounters along the way and deposits them at the bottom of the basin. In time, the water in the center of the basin grows richer in minerals like potassium, magnesium, boron and lithium.
