About Trimouns Talc Mine

The Trimouns talc mine near Luzenac in the Ariège Pyrenees, southern France, is one of the world’s largest talc producers and a globally significant collector locality for clinozoisite, dolomite-talc paragenesis, and rare alpine-cleft species. Active since 1905, it remains operational.

Geology

The deposit is a hydrothermal-metasomatic talc body formed by Mg-rich fluid alteration of Cretaceous-Triassic carbonate-pelite sequences during Alpine compression. Late-stage hydrothermal pockets produce gem clinozoisite and other species.

Notable Minerals

Talc (massive industrial-grade and collector-grade scaly aggregates), dolomite (gem rhombohedral crystals), clinozoisite (gem-clear pink to colorless prismatic crystals — world-class), epidote, dravite tourmaline, rutile, quartz, muscovite, magnetite. Trimouns clinozoisite is the species’ modern collector standard.

Collector Notes

Trimouns gem clinozoisite on dolomite/talc matrix is uniquely beautiful — pink-to-colorless prismatic crystals in pristine snow-white matrix. Active extraction continues through controlled mining contracts.
