A nice specimen of very lustrous long-needles quartz, space developed on the base of galena, sphalerite, and pyrite. Lately on quartz needles were developed calcite aggregates.
Тип минерал: pyrite
Galena, pyrite, sphalerite and quartz-rock crystal
An attractive specimen of well-terminated pyrite with very lustrous crystal faces, singenetically developed with transparent quartz – rock crystal and followed by sphalerite and galena.
Needle quartz with pyrite, galena and sphalerite
A specimen of shiny small galena and sphalerite crystals, followed by bigger pyrite crystals, particularly oxidated and coated by bornite. All these minerals are covered by extremely shiny, long-axes, needle quartz crystals, very well space developed and forming a set of crystals
Galena, sphalerite, pyrite and needle quartz-rock crystal
A very attractive specimen, presenting very well space developed long-axes transparent needle quartz, covering sphalerite, galena, and pyrite crystals
Quartz with rainbow pyrite
A unique for Bulgaria specimen presenting space developed transparent quartz – rock crystal with very well terminated shiny pyrite crystals coated by iridiscenting bornite and covellite as result of oxidation of , most likely coating of chalcopyrite
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
Needles quatz-rock crystal, pyrite, galena and sphalerite
A very aesthetic cabinet size specimen of long-axes needle quartz crystals, with very lustrous crystal faces, overgrowing base of combined sphalerite and galena small crystals and a little bigger pyrite crystals, showing in some places traces of oxidation and coating by bornite.
Needle quartz, pyrite and galena
A very aesthetic specimen of galena covered with small pyrite and overgrought by transparent , long axes, and very shiny quartz crystals
Cluster of two large galena crystals
A beautiful specimen presenting two large galena cubic crystals with very nice sculptures of the crystal faces showing the way of growth of the crystals. The specimen is actually floater what could be seen on the back part of the specimen, where down part of galena is dissolved and replaced by small crystals of pyrite and quartz.
Chalcopyrite, pyrite,galena and quartz
A specimen showing pseudomorph of pyrite after chalcopyrite. On the basement of galena was developed chalcopyrite crystal, lately dissolved and replaced by pyrite. On the other side of the specimen is developed spiral step mark of growing of galena crystal.
