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.
Тип минерал: pyrite
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.
Galena, pyrite, sphalerite and quarrtz – rock crystal
A beautiful cabinet size specimen presenting very well terminated galena crystals with sphalerite and pyrite, covered by thin long-axes transparent quartz crystals
Galena, sphalerite-marmatite, chalcopyrite and pyrite
One extraordinary specimen of galena on the top of black sphalerite- marmatite and chalcopyrite, followed by pyrite. Galena crystals are with rounded edges, due to strong dissolution
Manganocalcite with quartz, pyrite and sphalerite
One extraordinary specimen of single manganocalcite pink crystal, singenetically developed with small transparent rock crystal,green prazem quartz crystals, pyrite and sphalerite.
Qyartz with pyrite, chalcopyrite and sphalerite
One excellent thumbnail specimen of space developed thin quartz crystals, forming a net of crystals covered in some points with small pyrite, chalcopyrite and sphalerite crystals
Galena with chalcopyrite and pyrite
A very nice cabinet size specimen of galena, particularly covered by chalcopyrite. Galena is presented by cubic crystals with rounded edges, due to dissolution, and lately oxidated and coated in some parts by covelite. Chalcopyrite also shows change of color, to darker color, because of oxidation. Chalcopyrite is internally dissolved and replaced in some parts by shiny small pyrite crystals.
Rhodochrosite with quartz,pyrite and sphalerite
A large cabinet size and very attractive rhodochrosite specimen with very intensive pink color. Rhodochrosite is presented in two generations – one forming typical spherolites hemispheres, which is followed by sphalerite and pyrite and second which is with smaller crystals with intensive color, covering bigger part of earlier minerals. In the end crystallized small transparent quartz crystals
Golden calcite with galena, pyrite and sphalerite
An excellent cabinet size specimen of well shaped small crystals of galena, sphalerite and pyrite overgrowth by very lustrous rhombohedrons of golden color calcite with mosaic surface.
size 84 x 40 x 45 mm
A cabinet size group of pyrite crystals
A nice group of pyrite crystals with very well developed crystal faces with striation.
