Fluorite with Galena, Quartz

specimen number:
2341402

location:
Aouli, Mibladen, Ait Oufella Caidat, Midelt Cercle, Midelt, Draa-Tafilalet, Morocco

description:
Yellowish green cubic translucent crystals of fluorite, these lustrous and measuring to 2.6 cm in size, forming an attractive cluster with semi lustrous crystals of galena measuring to 1.2 cm and glassy gemmy crystals of colorless quartz to 1.0 cm. Arranged nicely and in very good condition. The specimen comes with two previous collection labels, one from Michel Perraudin and the other from Jan Erik Larsen.

The Aouli and Mibladen mining district near Midelt, Morocco, situated within the Upper Moulouya valley between the High and Middle Atlas mountains, features a complex geological setting where basement older rocks and Mesozoic carbonate host strata are cut by hydrothermal vein systems. Historically developed during the 20th century as a major industrial center for extracting lead ore, galena, and associated metals, the region is globally renowned among mineral collectors for yielding exceptional secondary minerals and gangue associates. Within these hydrothermal veins and cavity fillings, fluorite occurs alongside barite and quartz as a notable accessory and gangue mineral, reflecting the deep-seated fluid circulation and subsequent oxidation processes that shaped this famous metallogenic province.
