Mineralpedia Details for Caracolite
Named for the type locality at the Beatriz mine near the town of Caracoles in the Antofagasta region of Chile. Caracolite is a rare mineral that can be found in additional Chilean localities including the Generosa, Herminia, La Compania, and San Francisco mines in Antofagasta and the Buena Esperanza and Lolon mines in the Tarapaca region, as well as in Germany at the Auguste-Victoria mine in North Rhine-Westphalia, and in Ukraine. Caracolite occurs in oxidized chlorine-rich lead deposits as a secondary mineral. Caracolite will decompose in water and leave behind lead sulfate, PbSO4.
