Most manganese ores are from extensive layers of manganese-rich sedimentary rocks that formed in ancient oceans under specialized conditions. These occurred when changes in the oxidation state of ocean water first caused high concentrations of dissolved manganese and later precipitated various manganese minerals that became concentrated on the seabed. These layers are n

    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).
