Adamite

specimen number:
2063153

location:
Ojuela Mine, Mapimi, Durango, Mexico

description:
Lustrous translucent dark crystals of adamite to 0.8 cm in size set perfectly across the top of matrix. In great condition.

The Ojuela Mine, located in Mapimi, Durango, Mexico, was discovered by Spanish prospectors in 1598 and operated intermittently for over 350 years before closing commercially in 1932. Geologically, the deposit is hosted within deformed Cretaceous limestone units that have been intruded by Tertiary igneous rocks, creating an extensive hydrothermal pipe and vein system. Intense secondary oxidation processes acting on primary sulfide mineralization have produced a world-renowned zone of rich secondary mineral assemblages, making the mine famous for its exceptional variety of colorful arsenates, carbonates, and oxides.
