Geology & Origin

The Ojuela Mine near Mapimí in Durango is one of the world’s most important localities for secondary lead and arsenate minerals. The deposit is of hydrothermal origin and hosted in carbonate rocks. Oxidation processes in the upper parts of the ore veins led to the formation of vividly colored minerals such as Wulfenite and Mimetite. The combination of geochemical conditions, porous host rock and repeated mineral growth resulted in the exceptional diversity of forms and colors for which the Ojuela Mine is internationally renowned.
