    OverviewOccurrence and productionCharacteristicsHistoryApplicationsBiological rolePrecautionsEnvironmental health concerns

    Manganese comprises about 1000 ppm (0.1%) of the Earth's crust, the 12th most abundant of the crust's elements. Soil contains 7–9000 ppm of manganese with an average of 440 ppm. Seawater has only 10 ppm manganese and the atmosphere contains 0.01 µg/m . Manganese occurs principally as pyrolusite (MnO2), braunite, (Mn Mn 6)(SiO12), psilomelane (Ba,H2O)2Mn5O10, and to a lesser extent as rhodochrosite (MnCO3).
