Pneumatolytic acid type Sn-W mineralizations related to Oulmès (Walmes) granite.

Host rocks: Cambro-Ordovician graphitic and graphitoid-rich metapelites, close to Hercynian Walmès granite.
A HT-LP contact metamorphism aureole rims the granite : internal andalusite zone (chloritoid-staurolite), brown biotite zone and green biotite external zone.
Pegmatitic/hydrothermal beryl-cassiterite veins and quartz veins are frequent in tourmalinized micaschists wallrocks.
