An extraordinary cabinet size specimen of space developed quartz with galena, sphalerite, and chalcopyrite, secondary oxidized to bornite and covellite
Тип минерал: covelite
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.
Halcopyrite and quartz
An aesthetical specimen of large quartz crystals with also large chalcopyrite crystals, which secondary become subject to strong oxidation, what change the surface of the chalcopyrite and color it in red and on places blue color by forming coating of bornite and covelite
Quartz and chalcopyrite
Well shaped chalcopyrite crystals fallowed by white quartz crystals. Chalcopyrite is particlularly oxidated and coated by bornite and covelite. On some of the crystals some parts are coated by bonite and other by covelite, what most likely is due to dirrection of solutions flowing
