Nickeltalmessite crystals from Bou Azzer, Morocco – small cabinet specimen as unique piece
This small cabinet specimen features Nickeltalmessite from the world famous cobalt and nickel district of Bou Azzer, Morocco. The specimen is distinguished by its vivid yellow green to apple green mineralization covering large areas of the matrix. The crystals occur as fine crystalline aggregates and crusty coatings, creating a striking contrast against the brown host rock. The intense coloration and characteristic habit make this an attractive collector's specimen of a rare nickel arsenate mineral.
Geology & Origin
Nickeltalmessite is a rare hydrated nickel magnesium arsenate that forms in the oxidation zones of nickel and arsenic bearing deposits. Bou Azzer is one of the world's most important localities for nickel, cobalt and arsenate minerals and has produced numerous rare mineral species. The characteristic green coatings result from secondary weathering processes and are typical of the complex oxidation assemblages found at this locality. Specimens from Bou Azzer are highly valued by collectors for their vivid colors and mineralogical significance.
