Intrusive F/Li/Na/K-rich leucogranite (525-538 My) dome in granulitic gneisses.

Topaz (F)-muscovite (Li) granite in the deep parts of the cupola, topaz-zinnwaldite granite in the upper parts of the intrusion.

Frequent dykes of topaz-muscovite porphyric microgranite above the cupola.

These microgranites show miarolitic cavities with cassiterite (Ta), wolframoixiolite, ferberite, and scheelite.

Late-magmatic evolution of granites :
- Mobilization (by vapor fluids) of Sn in the miarolitic system.
- Transfer of W (liquid phase) in granites.
- REE are extracted by fluids from the deeper parts of the cupola and reconcentrated at the top of the intrusion.
- Loss of F and Li in topaz-muscovite granites and microgranites (extraction by a liquid phase).
