EV10Y1: New at Sainte-Marie-aux-Mines 2013
Fine specimen composed of isolated divergent groups of tabular Vanadinite crystals scattered over an unusual matrix of rhombohedral Siderite with well-defined crystals. The Vanadinite crystals show an intense orange-red color and good luster, contrasting with the dark Siderite matrix.
This specimen was published on the Mineralogical Record magazine's website, in its section 'What's New in the Mineral World?', 35th edition, August 14, 2013, and has been featured and photographed in the article 'Bergbau und Mineralien des Reviers Taouz, Marokko' in ‘Lapis’ magazine, on page 67 of issue number 3, 5-6/2026

Geologically, the Vanadinite formed in the oxidation zone of lead-bearing mineralizations, where vanadium-rich solutions reacted with primary lead minerals. The Siderite corresponds to an earlier hydrothermal stage and provided the substrate on which the Vanadinite crystals later developed.
