Constraints on Early Paleozoic Deep‐Ocean Oxygen Concentrations From the Iron Geochemistry of the Bay of Islands Ophiolite
Abstract The deep ocean is generally considered to have changed from anoxic in the Precambrian to oxygenated by the Late Paleozoic (∼420–400 Ma) due to changes in atmospheric oxygen concentrations. When the transition occurred, that is, in the Early Paleozoic or not until the Late Paleozoic, is less...
