"Galena is uncommon in pyrometasomatic deposits but does occur in Precambrian sulfide deposits of this type in central Sweden, in what were almost pure carbonate rocks. Associated minerals are in one deposit andradite and fluorite, but mostly magnesium-fluosilicates with tremolite or actinolite. Two contrasting deposits are associated with the same granite body; one is dominantly galena and other quite minor sulfides, the other is dominantly copper sulfides and galena is essentially absent. Thus, strong fractionation of sulfides must have occurred."
