Les Malines is a major deposit Pb-Zn-Ag deposit located in the Cévennes massif near Le Vigan.
Several mines were very active since the Middle Age and the modern mining works, operated by the Peñarroya-Metaleurop company, shut down in 1991 after producing almost 1 million tons of metal.
Les Malines became famous in the mineral collection world in the 1980's when the modern mine sections of Les Cèdres and La Sanguinède hit a succession of fantastic pockets with outstanding baryte balls or bournonite crystals, the two 'star' species of the deposit, which also shed light on other small but finely crystallized species like sphalerite, tetrahedrite, smithsonite, calcite...
You have here a sphalerite specimen of the best quality from Les Cèdres, displaying highly lustrous polysynthetic crystals with translucent areas that reveal red-brown and cleiophane green zonations!
Notice also a small but finely crystallized galena crystal on the left of the specimen.
The sulphides are scattered over sparkling clear micro quartz, coating a piece of grey dolostone matrix.
