Quartz-bournonite vein on the right bank of Allier river, along the road between Lavoûte and Chilhac.
Tha quartz is macrocrystalline, hyaline, with "cockade" structure. Presence of barite replaced by quartz.
Late calcite in quartz vugs and calcite veins in the deep zone.
Old exploration gallery along river Allier in a calcite vein (several generations of quartz and calcite, illite 2M2).
Host rocks : leptyno-amphibolitic group.
