Vanadinite

Vanadinite from the Touissit–Bou Beker Mining District, Jerada Province, Orental Region, Morocco, measuring 60 × 56 × 24 mm and weighing 113 grams. The specimen shows a closely packed mineral surface that rewards examination in the detail views. This is a district-specific Moroccan specimen, with an attribution that distinguishes it from Vanadinite collected in other parts of the country.

Vanadinite is a lead vanadate containing chloride and belongs to the Apatite group. It is associated with the alteration of lead-bearing deposits, where vanadium becomes incorporated into a new mineral. That chemistry provides a useful comparison with related lead phosphates and arsenates, allowing a collector to explore structural relationships as well as the visual differences between species.

The Touissit–Bou Beker district is the geographical focus of this piece. Its 60 mm maximum span and relatively shallow depth give a clear sense of scale, while the closer photographs allow the mineral surface to be explored. Keeping the district attribution with the specimen makes comparisons with other Moroccan Vanadinites more informative than a country-only label would allow. This example comes from the David Vince Collection. The collecting appeal lies in the combination of a specific Moroccan district and a mineral whose chemistry connects it with several other important lead species. It can contribute to a locality display or a systematic Apatite-group collection, with the provenance preserving the later history of this particular specimen.
