One excellent and very interesting cabinet size specimen of galena on mother rock, overgrown by clear quartz crystals, and later covered by limonite. Later, on galena and limonite crystalize unidentified secondary copper mineral (probably result of weathering of chalcopyrite) with beautiful turquoise color. The specimen was found in the fault zone in the abandoned mine in conditions of intensive weathering with water, in the last 30 years.
Тип минерал: chalcopyrite
Galena, calcite, sphalerite, chalcopyrite, bornite, covelite
A very interesting specimen, of black sphalerite – marmatite and chalcopyrite, overgrowth by large galena cubic crystals, followed by flat rhombohedral calcite crystals. In the late stage of crystallization, galena was strongly dissolved and some of the crystals are particularly destroyed. Could be seen typical „fingerprint“ dissolution, but the surfaces stay mirror lustrous. Probably the same process was the reason for appearance of „rainbow chalcopyrite surfaces“ – the result of the coating by bornite and covellite.

Quartz, galena, chalcopyrite
One very aesthetic specimen of 3 large quartz crystals on the top of galena and chalcopyrite crystals, overgrowth by the second generation small quartz crystals
Quartz – rock crystal, chalcopyrite, galena, sphalerite
An amazing, cabinet size specimen of thin transparent, and very lustrous quartz crystals, developing the space net, singenetically developed with small chalcopyrite crystals,galena, and sphalerite crystals.
Galena, quartz, sphalerite, chalcopyrite
One very aesthetic specimen o transparent quartz crystals, overgrowth slightly dissolved galena, sphalerite, and chalcopyrite
Quartz, chalcopyrite, sphalerite, galena
One very aesthetic cabinet size specimen of quartz overgrowth by sphalerite, chalcopyrite and second-generation thin quartz crystals. Part of chalcopyrite crystals are coated by bornite and covellite.
Chalcopyrite, galena, sphalerite, pyrite
An amazing miniature specimen of lagre, chalcopyrite crystals, internaly corroded and replaced by galena, sphalerite and pyrite. Chakcpyrite is strongly oxidized and surface in some parts is coated by bornite.
Rhodochrosite, sphalerite-marmatite, galena, quartz, pyrite, chalcopyrite and calcite
One extraordinary cabinet size specimen, with full paragenesis set of minerals of mine Eniovche. On quartz base, were developed rounded small rhodochrosite crystals with intensive color were developed sphalerite, galena, pyrite, and calcite.
Chalcopyrite, quartz, pyrite and sphalerite
A beautiful cabinet specimen of sphalerite and chalcopyrite followed by pyrite, which corroded chalcopyrite by internal replacement, in some places breaking from inside mother chalcopyrite crystals. #1373
Rhodochrosite, stilbite, chalcopyrite and sphalerite
One amazing cabinet size specimen of rhodochrosite, covered by stilbite, and with one sphalerite crystal with chalcopyrite
