It comes from the Beauvoir de La Bosse kaolin quarry at Échassières in the Allier department.
The gîte is also known by other local names, such as “Beauvoir” or “Les Montmints”.
Cassiterite and wolframite are minerals frequently found in deposits associated with granites transformed into kaolinite.
Wolfram was mined for weapons and light bulbs.
This sample comes from the collection of Denis Galmier, a geological engineer born around 1910, who devoted his life to the study of French metalliferous deposits. Supplied with label.
