A stratigraphic scanning electron microscope tour showing the evolution of manganese-oxide mineralization of host sediment. Mn mineralization shows a multipronged process of formation including growth of Mn columns in soft sediment, cementation and then partial to complete replacement of the host sediment, Mn grain growth, Mn recrystallization, and late-stage void-fracture fill. Click image for full explanation. A new study led by USGS describes a previously undocumented style of hydrothermal manganese-oxide mineralization on the seabed near American Samoa, offering new insight into how seafloor mineral occurrences can form and how widespread similar deposits may be around the world. The study examined 24 dredge samples collected from three sites along the Samoan volcanic chain in the South Pacific. In many of these samples, researchers found evidence that hot, mineral-rich fluids moved upward through seafloor sediments, progressively replacing the original material with thick layers of manganese-oxide minerals. Hydrothermal systems occur where heated fluids circulate through Earth's crust and return to the seafloor, carrying dissolved metals and other elements. When those fluids encounter cooler surroundings, minerals can precipitate and accumulate. Manganese oxides are common components of seafloor mineral occurrences, but the new study documents something researchers had not previously observed: hydrothermal manganese oxides replacing sediment made up of foraminiferal carbonate. Foraminifera are microscopic marine organisms whose shells are commonly composed of calcium carbonate and can accumulate on the seafloor after the organisms die. (Credit: USGS)
