Galena,chalcopyrite, sphalerite and quartz

One attractive specimen presenting almost full paragenesys set of deposit Madan. Very well shaped and shiny sphalerite crystals singenetically developed with lustrous galena crystals, showing „waves“ of dissolution, and corroding together with sphalerite, pyrite and quartz dissolved chalcopyrite.

Chalcopyrite with galena sphalerite-marmatite and pyrite

An excellent, large cabinet size specimen presenting almost full sulfide paragenesys of deposit Madan. Large crystals of chalcopyrite was dissolved and particularly replaced by pyrite, galena and black sphalerite- marmatite.

Pyrite after chalcopyrite pseudomorph with bornite and covelite

An extraordinary specimen showing typical for Madan secondary dissolvation and replacement of chalcopyrite by pyrite. The large chalcopyrite crystals are internaly dissolved and replaced by sphalerite and pyrite. In the end of mineralisation process, take part oxidation and coating of chalcopyrite by bornite and covelite
