manganese (Mn) - David Darling

Pyrolusite is a soft, gray-black oxide mineral composed of manganese (IV) oxide (MnO 2). Of widespread occurrence, pyrolusite (pyrolucite) is the chief ore of manganese. It is a secondary mineral formed as a precipitate in lakes and bogs at low temperatures, often in veins of quartz, but also occurs as manganese nodules on the floor of the Pacific Ocean.
