An excellent double terminated group of two quartz crystals, overgrought by well developed chalcopyrite followed by sphalerite and second generation quartz.
Тип минерал: chalcopyrite
Space developed quartz-rock crystal with chalcopyrite,sphalerite and galena
An extraordinary cabinet size specimen of space developed quartz with galena, sphalerite, and chalcopyrite, secondary oxidized to bornite and covellite
Pseudomorph of pyrite after chalcopyrite and galena
An excellent, large cabinet size specimen, presenting galena crystalized on chalcopyrite, and after particular desolvation, corroded by pyrite replacing chalcopyrite and galena
Chalcopyrite and sphalerite-marmatite
A miniature size specimen of excellently developed chalcopyrite crystals particularly covered by sphalerite – marmatite and quartz.
Skeletal melted galena with chalcopiryte
An extraordinary and very aesthetic galena crystal with skeletal development, followed by chalcopyrite. In the later stages of development of the deposit, galena was strongly dissolved to forming „fingerprint“ on crystal faces
Excellent cabinet specimen of quartz after calcite pseudomorph with chalcopyrite
An excellent cabinet size specimen of quartz after calcite pseudomorph with chalcopyrite. Thin calcite, steep scalenohedron crystals, were covered by quartz and at the end, of one side of the crystals was developed small chalcopyrite crystals.
Rhodochrosite, stylbite and chalcopyrite
Excellent cabinet size specimen of small curved rhodochrosite crystals, covering some chalcopyrite crystals and followed by white stilbite crystals
Galena, chalcopyrite sphalerite and green quartz – prazem
A beautiful specimen presenting well-terminated galena cubic crystals, covered by chalcopyrite and sphalerite-marmatite with green quartz on the top.
Chalcopyrite pseudomorph with pyrite, galena, sphalerite and quartz
A large cabinet size specimen, presenting almost full paragenesis of Madan with very complicated mineralization process. Pseudomorph of pyrite after chalcopyrite, on the top of small galena crystals, followed by quartz and small sphalerite (cleophane) crystals
Chalcopyrite, quartz, galena, sphalerite, bornite and covelite
An aesthetic cabinet sized specimen of large chalcopyrite crystals, singenetically developed with galena and sphalerite, followed by quartz. In the last stage of crystallization, oxidation creates a thin coating of bornite and covellite.
