specimen number:
2341421

location:
Oumjrane, Alnif Cercle, Tinghir, Draa-Tafilalet, Morocco

description:
Colorless gemmy lustrous tabular crystals of barite measuring to 3.3 cm in height standing up from a crystalline quartz matrix. This is basically a floater that is complete all around with no points of attachment. In excellent condition. The specimen comes with a previous label from the collection of Jan Erik Larsen.

The Oumjrane mining district, situated in the eastern Anti-Atlas region of Morocco, features a complex geological setting composed of deformed Paleozoic sedimentary rocks, including sandstone, quartzite, and shale formations, cut by regional faults and hydrothermal veins. The area has a long mining history that dates back centuries, with traditional and small-scale colonial-era French workings targeting rich polymetallic veins. Modern commercial extraction and localized prospecting have since revived the district, making it globally famous among mineral collectors and geologists for producing vibrant secondary copper specimens and associated crystallization matrices from its desert and underground deposits.
