  What is rhodochrosite? Rhodochrosite  is a pink to red manganese-containing carbonate mineral that usually contains calcium, iron, zinc and other elements.  Rhodochrosite  usually appears rose red or pink and is called rhodonite or rhodonite in the gem industry. Origin of  Rhodochrosite Rhodochrosite is mainly formed by the following four causes: Sedimentary origin:  In low-oxygen sedimentary environments such as oceans, lakes, and lagoons, divalent manganese ions and carbonates in water combine to form rhodochrosite. Hydrothermal origin:  Manganese-containing hydrothermal fluids rise along cracks and react with surrounding rocks to form rhodochrosite. Metamorphic origin:  During the regional metamorphism of sedimentary manganese deposits or carbonate rocks, manganese-containing minerals are recrystallized to form rhodochrosite under high temperature and high pressure conditions. Weathering origin:  Primary manganese minerals are dissolved ...
