Mindat Locality ID:

65356

Long-form identifier:

mindat:1:2:65356:8

GUID (UUID V4):

Quartz vein in pyritized migmatitic granite, near the South Armorican mylonitized zone at the contact leucogranite/gneisses and migmatitic granite.
Three phases of mineralization are known :
1) Berthierite and pyrrhotite in quartz, altered into stibnite, antimony, pyrite-marcasite
2) Alteration of the first deposition by Pb-Zn solutions, formation of zinkenite, sphalerite and sulphosalts
3) Late dissolution and formation of jamesonite, galena, pyrite framboids in chalcedony
