Little is known about marine mineral deposits in the Arctic Ocean, an ocean dominated by continental shelf and basins semi‐closed to deep‐water circulation. Here, we present data for ferromanganese crusts and nodules collected from the Amerasia Arctic Ocean in , , and (HLY, HLY, and HLY).Cited by: Get this from a library!

Redox-sensitive metallic elements, Mn and Fe, are oxidized in deep sea waters and form abundant ferromanganese crusts and nodules on the world’s ocean floors at ultraslow rates of : A. Usui, H. Hino, D. Suzushima, N. Tomioka, Y. Suzuki, M. Sunamura, S. Kato, T. Kashiwabara, S. Kiku. Manganese nodules, together with micronodules and encrustations, are ferromanganese oxide deposits which contain variable amounts of other elements (Table 1).They occur throughout the oceans, although the economically interesting varieties have a much more restricted distribution. Manganese nodules are spherical to oblate in shape and range in size from less than 1 cm in diameter up to 10 cm.
The Pb-, Nd-, and Sr-isotope compositions of oceanic ferromanganese deposits, together with the Nd-, and Sr-isotope compositions of altered ocean-floor basalts are reported. These data are used to evaluate the sources of these metals in both the oceans and ferromanganese deposits and the extent to which ocean-floor basalts are a source of, or a sink for these metals.

Ferromanganese deposits are the most common and probably the best-known authigenic deposits found on the deep-ocean seafloor. These occur as encrustations or crusts on submarine rock outcrops, or as discrete nodules and concretions.
The Nd isotopic compositions of hydrogenous ferromanganese encrustations and nodules largely reflect those of the overlying seawater, integrated over the few millions of years over which they grow. Available Nd isotope data on ocean-floor hydrogenous deposits suggest control by Nd from particulates blown from the continents and released by Cited by: Ferromanganese crusts are the most technically challenging deep-ocean mineral deposits to recover because they are firmly attached to often steep and uneven rock surfaces (Fig.
4A). Test mining of Fe–Mn nodules and seafloor massive sulfides has already been undertaken. Ferromanganese deposits cover about 46 million km 2 of the ocean floor, at water depths ranging from 3 to 6 km. The nodule deposits are typical two‐dimensional bodies, most commonly occur at the sediment–water interface and vary in abundance from being thinly scattered in some places to densely populated in other areas, often exceeding 10 kg/m 2.

These deep-ocean mineral deposits are windows into Earth's processes, revealing clues to the evolution of seawater and ancient ore-forming processes.

Deep-Ocean Ferromanganese Crusts and Nodules. Little is known about marine mineral deposits in the Arctic Ocean, an ocean dominated by continental shelf and basins semi-closed to deep-water.
Radiolarian oozes of the North Pacific are the most porous, water-laden materials of any ocean floor. Diatomaceous sediments have bulk properties between those characteristic of red clay and radiolarian ooze. Carbonate oozes of the North Atlantic have a wider range of properties than their North Pacific by: ents Deep-Ocean Mineral Deposits: Metal Resources and Windows into Earth Processes.
THE BLUE PLANET: EARTH’S FINAL FRONTIER. The Earth’s oceans form a continuous body of saltwater covering more than File Size: 4MB. ADVERTISEMENTS: 2 Most important types of ocean deposits are: 1. Terrigenous Deposits 2. Pelagic Deposits. There are unconsolidated sediments, deposited on the ocean floor.
These are ocean deposits. They vary from location to location. ADVERTISEMENTS: The study of ocean deposits is important in understanding the rocks exposed on the earth’s surface which were once laid [ ]Missing: Ferromanganese.
Abstract. Marine iron manganese deposits show a greater chemical variability than was realized only 10 years ago. As a consequence correct conclusions regarding the genesis of a given deposit frequently require knowledge about several geochemical parameters and preferably about accumulation rates and spatial relations vis-a-vis e.g.

Yaltanets, A. Myaskov, V. Drobadenko, D. Pastikhin. Abstract. The pioneering HMS Challenger expedition of opened the era of great geologic discoveries on the sea floor.
Unusual mineral deposits were among the remarkable findings (Murray and Renard ). On 18 Februarymiles southwest of the island of Ferro in the Canary Island Group, the Challenger recovered deep-sea manganese nodules enriched in metals such as copper, Cited by: 1.
In marked contrast, their concentrations in pelagic clays and ferromanganese deposits occurring on the ocean floor are many orders of magnitude greater. This relationship is a Cited by: RECENTLY, one of us has advanced arguments 1 in support of the idea that manganese-rich deposits of the sea floor may result from the metabolic activity of Cited by: A key question for the future management of the oceans is whether the mineral deposits that exist on the seafloor of the deep ocean can be extracted without significant adverse effects to the environment.
The potential impacts of mining are wide-ranging and will vary depending on the type of metal-rich mineral deposit being by:
