Galena chalcopyrite, bornite, covellite, pyrite

One very aesthetic – autumn style specimen of chalcopyrite, developed on the base of quartz crystals. Chalcopyrite is secondarily corroded (dissolved and replaced)  by pyrite, and the internal pressure of crystalizing crystals crack the mother crystals and cemented these cracks. Chalcopyrite is coated by bornite and covellite during the oxidizing of their surface.

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
