Chalcopyrite, pyrite, sphalerite, quartz, galena

One beautiful cabinet size specimen with an almost full set of paragenesis minerals in Madan. Well developed sphalerite-marmatite crystals, growing singenetically with spinel law twinned galena and large chalcopyrite crystals, particularly corroded and replaced by pyrite. At the end of the crystallization process, chalcopyrite was oxidized on the surface to bornite and covellite.
