Rhodochrosite, Quartz and Pyrite crystals from the Kassandra Mine, Chalkidiki, Greece – small cabinet specimen as unique piece
This small cabinet specimen shows a characteristic association of Rhodochrosite, Quartz and Pyrite from the Kassandra Mine, Chalkidiki, Greece, originating from the Gerd Tremmel collection. The specimen is dominated by pink to salmon colored, platy Rhodochrosite crystals forming stacked, tabular aggregates. Parts of the surfaces are covered by fine crystalline, light colored Quartz, giving the Rhodochrosite a slightly matte to sugary appearance. Pyrite is present only in a subordinate manner and does not form prominent individual crystals. The crystals are clearly recognizable overall, although they mainly occur as intergrown aggregates, resulting in a calm and well structured appearance.
Geology & Origin
The Kassandra Mine is one of the most important polymetallic deposits in Greece and is well known for its carbonate and sulfide rich mineral parageneses. Rhodochrosite formed from hydrothermal solutions depositing manganese rich fluids within fractures and cavities. Quartz commonly accompanies these processes as a later or contemporaneous precipitation, while Pyrite represents a typical sulfide mineral of the deposit. The association of these minerals reflects the complex hydrothermal evolution of the district and makes specimens from Kassandra valuable reference and collector pieces.
