About Mibladen Mining District
The Mibladen Mining District in the High Atlas region of Morocco is the world’s premier source of crystallized vanadinite — the brilliant red-orange Pb-V chloride that defines the species. Active since the 1920s, Mibladen has produced more aesthetic vanadinite specimens than any other locality on Earth.
Geology
The deposits are oxidized Pb-Ba-V mineralization in Triassic-Jurassic sandstones and conglomerates. The Pb-rich primary ore underwent extensive oxidation under V-bearing groundwater conditions, producing thick V-rich oxide caps with vanadinite as the dominant V phase.
Notable Minerals
Vanadinite (intense red-orange hexagonal hopper-faced crystals on barite or limonite matrix — world archetype), barite (gem-clear tabular plates, including yellow and orange varieties), cerussite (gem-clear twins), pyromorphite (yellow-green hexagonal prisms), mimetite (orange to yellow hexagonal), wulfenite (orange tabular), galena, calcite. The “vanadinite on barite” combination is a Mibladen signature.
Collector Notes
Mibladen vanadinite is essentially the species’ display benchmark globally. Top specimens with intense red-orange color and gem-clear crystal terminations command premium prices at Tucson and Munich gem shows.
