Alloclasite crystals from the Bouismas Mine, Bou Azzer, Morocco – miniature specimen as unique piece
Alloclasite crystals on this miniature specimen occur as densely intergrown, metallic silvery grey to steel grey aggregates with a distinctly scaly to fibrous surface texture. Individual crystals are not freely developed, yet the crystalline nature is clearly visible through the fine, parallel oriented structure. The surface displays a characteristic metallic luster with locally silky reflections, which is typical for Alloclasite from the Bou Azzer district. The specimen consists of compact crystalline aggregates on matrix, without clearly isolated single crystals.
Geology & Origin
Alloclasite is an iron arsenide that typically forms in hydrothermal ore veins, commonly associated with cobalt, nickel, and arsenic minerals. The Bouismas Mine within the Bou Azzer district is among the world’s most important localities for arsenide related cobalt mineralization. Alloclasite crystals from this area are well known for their distinctive aggregate habits and metallic appearance. Specimens originating from the Gerd Tremmel collection additionally hold significant historical and scientific importance.
