El Desierto is one of about sixty sulfur deposits in Bolivia, all located on the chain of volcanoes that forms the Western Andes cordillera along the border between Bolivia and Chile. At most of these deposits, the native sulfur is massive, occurring as the cementing agent in volcanic ash, but in three deposits, including El

In 2023, China produced around 19 million metric tons of sulfur, making it by far the world's leading sulfur producer. Sulfur is one of the most common chemical elements found in nature.
Abstract. Native sulfur occurrences, which are very common in the Andes of northern Chile (18–28° S lat), are usually found directly related to summits, craters, and/or along flanks in almost all Upper Cenozoic volcanic edifices, mainly as sulfur mantos, breccias, veins, …
