location:
Aghbar Mine, Tansifte Caidat, Agdz Cercle, Zagora, Draa-Tafilalet, Morocco

description:
A beautiful example for this mineral, lustrous green translucent crystals to 0.3 cm in size and lining a large open pocket within matrix. From 2011, this is in super condition and comes with a label from the collection of Jan Erik Larsen.

The Aghbar Mine, located within the Bou Azzer district of the Anti-Atlas mountains in Morocco, is part of a premier cobalt and nickel mining region with industrial exploration and extraction ramping up significantly under twentieth-century colonial and modern state operations. Geologically, the deposit is situated within the central part of the Bou Azzer-El Graara inlier, where Cryogenian serpentinite masses are faulted against Ediacaran volcanic and sedimentary formations, creating complex hydrothermal vein systems. Mineralogically, the mine is world-famous among collectors and researchers for yielding exceptional secondary arsenate and cobalt-bearing species, most notably brilliant purple roselite, calcite, and wendwilsonite, alongside rich assemblages of primary cobalt and nickel arsenides.
