Manganese Ore Deposits

Manganese ores can be carbonates, usually rhodochrosite but sometimes kutnahorite, or various silicates and oxides, the most common being braunite, bixbyite, and hausmannite [see table of common minerals]. The carbonates carry useful isotope signals for C and O [see stable isotopes of Mn deposits].
