Chalcopyrite, sphalerite-matmatite, pyrite, galena, quartz and dolomite

#2653
One very attractive large cabinet size specimen of quartz, overgrowth by large chalcopyrite crystals in combination with sphalerite-marmatite and galena. In some parts, chalcopyrite is corroded by small pyrite crystals, which is common in this mine. In the last stages of crystallization dolomite, coated with limonite formed small round crystals of all previously crystallized minerals.

Cluster of galena, sphalerite, pyrite, and thin needle quartz

One exceptional and very aesthetic cabinet size specimen of small cubic and very lustrous galena and pyrite crystals, covered by very thin clear small quartz crystals, very interesting arranged in the space, forming the starts like groups of crystals.

Quartz, chalcopyrite, sphalerite-marmatite and dolomite

One excellent miniature specimen of clear quartz crystals overgrowth  by several twined and very well terminated chalcopyrite crystals, followed by black and very lustrous sphalerite – marmatite tetrahedral crystals, covered by round yellow-orange dolomite

Rainbow pyrite, sphalerite and galena

An excellent cabinet size specimen of small galena and sphalerite crystals, overgrowth by very lustrous pyrite crystals lately, in the process of oxidation, coated by bornite and covellite.

A very rare transparent sphalerite -cleophane, sphalerite-marmatite, galena and quartz

One extremely rare specimen showing both varieties of sphalerite – cellophane (cleiophane) and marmatite. The large green transparent to translucent sphalerite – cleophane isometric crystal, was developed on quartz and galena and lately was overgrowth by small black opaque tetrahedral crystals of marmatite, which shows the evolution in feeding hydrothermal solutions.

Quartz-rock crystal, sphalerite-marmatite and pyrite

A very aesthetic cabinet size specimen of transparent well-formed quartz crystals, overgrowth by black and very lustrous sphalerite-marmatite crystals overgrowth by very well terminated lustrous pyrite crystals
