Abstract:
Behavior of copper under formation of sulfide-free ore-bearing metasomatites of the Pelagonian massif, Republic of North Macedonia has been studied. It is shown that there was a maximum of copper activity in the process of ore formation which resulted in the crystallization of Cu-bearing rock-forming silicates and oxides with complete absence of sulfides and sulfosalts. Before the stage of the decline in the activity of copper, it concentrated mainly in Pb- and Zn-containing arsenates and vanadates of the adelite–descloizite group, which replaced primary rock-forming tilasite.
