An extraordinary specimen of very well terminated cubic galena crystals, overgrowth bigger, mosaic galena crystal with singeneticaly developed sphalerite-marmatite.
Тип минерал: galena
Galena with skeleatl sphalerite – marmatite and quartz
One small, but very nice specimen build in black and opaque sphalerite- marmatite around big transparent quartz crystal. Sphalerite is with skeletal development, overgrowth by large well-terminated cubic galena crystals.
Galrena with black sphalerite – marmatite
One very aesthetic specimen of galena with black, lustrous well shaped crystals of sphalerite-marmatite.
Skeletal galena crystal with sphalerite and quartz
One very well developed cabinet size specimen showing skeletal developed galena crystal on sphalerite and quartz.
Galena,chalcopyrite, sphalerite and quartz
One attractive specimen presenting almost full paragenesys set of deposit Madan. Very well shaped and shiny sphalerite crystals singenetically developed with lustrous galena crystals, showing „waves“ of dissolution, and corroding together with sphalerite, pyrite and quartz dissolved chalcopyrite.
Quartz „stars“ on galena and sphalerite
A large cabinet size specimen of very well space developed quartz crystals on the top of galena and sphalerite small crystals. Quartz is very well space developed, with white translucent crystals, starting their growth form one point in all directions, forming „stars“ of crystals.
Galena with mosaic development of the crystals
An excellent large cabinet size specimen with mosaic development of the crystals. This kind of aggregates are usually due to overgrought of large single crystal. One, some or all of the faces, start to grow with mosaic step mode and due ( most likely) to fast crystallization and unequal concentration of solutions, develop single crystal with individual temp of growing, but with joined direction of development and isolated crystals with inherited orientation.
Chalcopyrite with galena sphalerite-marmatite and pyrite
An excellent, large cabinet size specimen presenting almost full sulfide paragenesys of deposit Madan. Large crystals of chalcopyrite was dissolved and particularly replaced by pyrite, galena and black sphalerite- marmatite.
Quartz – rock crystal with galena crystal
An interesting specimen of group of long axes transparent quartz (rock crystal), overgrought by single galena crystal
Green sphalerite – cleophane with exceptional transparency on the top of galena
One exceptional, large cabinet size specimen, with green sphalerite and very high transparency, developed on the top of galena crystals and chalcopyrite. Specimen has a cut base.
