rhodochrosite

Colorado officially named rhodochrosite as its state mineral in 2002.

Her name is based on Inca Rose, a term sometimes used to describe the mineral rhodochrosite.

Manganoan calcite is sometimes confused with rhodochrosite.

Manganese carbonate occurs naturally as the mineral rhodochrosite.

Gemstones include rubies, diamonds, rhodochrosite, opal, emerald, and amethyst among others.

This oxidation state is also seen in the mineral rhodochrosite (manganese(II) carbonate).

Kutnohorite occurs typically in manganiferous sediments, associated with rhodochrosite, aragonite and calcite.

Manganese occurs as replacement bodies of pyrolusite and rhodochrosite in limestone adjacent to the fracture zones.

Banded rhodochrosite is mined in Capillitas, Argentina.

The swirling patterns suggest blowups of agate, malachite, rhodochrosite and other mineral stones that have been cut and polished.

It forms two limited solid solution series, with substitution of manganese leading to rhodochrosite, and with iron, leading to siderite.

Associated minerals include spessartine, tephroite, alleghanyite, hausmannite, pyrophanite, alabandite, rhodonite and rhodochrosite.

Fe-montmorillonite, goethite, hematite, siderite, rhodochrosite, pyrite, sphalerite, anhydrite.

A good example of isomorphism classification would be the calcite group, containing the minerals calcite, magnesite, siderite, rhodochrosite, and smithsonite.

It occurs with acanthite, calcite, chalcopyrite, galena, pyrite, quartz, rhodochrosite, rhodonite, sphalerite and native tellurium.

Catamarca, Argentina has an old Incan silver mine that has produced fine stalactitic examples of rhodochrosite that are unique and very attractive.

Sonolite has been found in association with calcite, chlorite, franklinite, galaxite, manganosite, pyrochroite, rhodochrosite, tephroite, willemite, and zincite.

Specimens of Sweet Home Mine rhodochrosite are also displayed at the geology museum at the Colorado School of Mines.

Birnessite is found as an oxidation product of several other minerals, including rhodonite, rhodochrosite, and as a weathering product of franklinite-wilminite ore.

It occurs with mooreite, willemite, fluorite, hydrozincite, pyrochroite, zincite and rhodochrosite at Sterling Hill, New Jersey.

At the Ryujima Mine, Nagano Prefecture in Japan, magnesian kutnohorite occurs with quartz and rhodochrosite.

In one case are some of Mr. Heyer's favorite minerals, and he enjoys pointing out the blue-black covelite, the emerald-green antlerite, and the rosy-looking rhodochrosite.

Sylvanite is associated with native gold, quartz, fluorite, rhodochrosite, pyrite, acanthite, nagyagite, calaverite, krennerite, and other rare telluride minerals.
