ABSTRACT
At the Kondro hill, Pindos ophiolite complex, massive sulfide ore is hosted in diabase. Chalcopyrite occurs in two different generations. The first generation (stage I) is represented by coarse grained chalcopyrite, bornite and pyrite, all being Se-free. The second generation of chalcopyrite (stage II) forms intergrowth with sphalerite in veinlets penetrating the earlier ore (stage I). The chalcopyrite - sphalertite assemblage shows up to 1.0 wt% Se, connected with clausthalite (PbSe) hosted exclusively within chalcopyrite II.
