Galena, chalcopyrite, pyrite and quartz

One very nice cabinet size specimen, presenting group of large galena crystals with signs of dissolution on the top of chalcopyrite corroded and replaced by pyrite, followed by quartz.

Needle quartz with pyrite

One beautiful specimen of very aesthetic, perfectly shaped thin quartz crystals with very lustrous crystal faces with well developed pyrite crystals,slightly oxidized  to red color.

Quartz cluster with pyrite

One large cabinet size cluster of well developed mosaic quartz crystals developed together with pyrite crystals which start their development inn the last stages of growing of quartz. As result part of the pyrite crystals are inside quartz and the rest is on the top of the crystals.

Rare green quartz – prazem, galena, pyrite, chalcopyrite and quartz

One beautiful and rare cabinet size specimen, presenting almost full paragenesis set of Madan deposit. Galena is with large cubic skeletal crystals and mosaic developed crystal faces, overgrowth by large green quartz crystals and chalcopyrite, which is secondary oxidated and replaced by pyrite well shaped shiny crystals.

Chalcopyrite, pyrite and galena

One very interesting specimen of chalcopyrite and pyrite on mother rock, followed by galena. Chalcopyrite is internally corroded and replaced by small pyrite crystals. Galena crystals are particularly corroded and coated by bornite.
