Sulfur

specimen number:
9892071

location:
El Desierto mine, San Pablo de Napa, Daniel Campos, Potosi, Bolivia

description:

Brilliant yellow almost gemmy crystals of sulfur measuring to 0.8 cm in size on matrix. Some damage present, the prominent crystals are in good condition.

The El Desierto mine, situated in the remote volcanic high altitude of the San Pablo de Napa region in the Daniel Campos Province of Potosi, Bolivia, is a specialized small scale deposit historically worked on and off for native sulfur extraction rather than having a formalized corporate operating timeline. Geologically, the deposit is tied to the intense volcanic and fumarolic activity of the Andean Altiplano, where sulfur bearing gases have migrated upward and condensed near the surface. This low temperature geothermal activity resulted in the precipitation of exceptionally pure, vibrant canary-yellow orthorhombic sulfur crystals, often forming bipyramidal, tabular, or skeletal habits within local matrix cavities.
