Mineralpedia Details for Rhodochrosite
Named for the Greek rhodon, meaning “rose” and chrosis, meaning “coloring.” Rhodochrosite is found in low-temperature to mid-temperature hydrothermal vein deposits, metamorphic rock, commonly in carbonatites, in sediments either as an authigenic or secondary mineral, and occasionally in granite pegmatites. Hundreds of widespread localities, but fine crystals may be found in Romania, Germany, Russia, Canada, the USA, Mexico, Peru, Argentina, South Africa, and Japan.
