rock-hosted deposits can also be identified: those with Mn derived via upwelling from oxygen-minimum zones and...additional strong peak in the Oligocene. Therefore, Mn is not controlled entirely by the level of oxygen...oxygen in the Earth’s atmosphere. At each peak of Mn deposition, the associated ore deposits are concentrated...There is a conspicuous gap in sedimentary rock-hosted Mn deposits between 1800 and 800 Ma that may correspond...but one without sulfidic deep water. Alternatively, Mn may have been precipitated entirely in the deep ocean
