Manganese Nodule an overview ScienceDirect Topics
Manganese nodules (also referred to as polymetallic nodules) are spherical precipitates of manganese, iron oxides and other metals (eg, copper, cobalt, and zinc) that form around a core material, such as a shell fragment or shark's toothLarge amounts of manganese can be found in marine manganese nodules Manganese is the first element of the group VII B elements with the atomic number 25, followed by technetium and rhenium Its atomic weight is 5494 g, the melting point is 1246 °C, and the boiling point is 2061 °C The electronic configuration of manganese is 3d 5 4s 2Manganese Nodules an overview ScienceDirect Manganese and iron oxide mineral deposits formed on or just below the sedimentcovered surface of the deepocean seabed by accretion (precipitation) of oxide layers around a nucleus, thereby(PDF) Manganese Nodules ResearchGate
Manganese nodules « World Ocean Review
The formation of the manganese nodules is conceivably simple Dissolved metal compounds in the sea water precipitate over time around a nucleus of some kind on the sea floor The growth core can be, for example, a shark’s tooth or a fragment of a Manganese nodules can be found in different types of environments, such as freshwater lakes, fjords, continental shelves, seamounts, plains, and abyssal basins [ 25 ] The nodules are scattered at the sediment–water interface but are also found, mainly, at the water interface of the seabed and buried in the sediment [ 26 ]Minerals Free FullText Manganese Nodules in Nodule sizes range from mere mm in diameter to over 30 cm (although the average appears to be around 8 cm) depending on their geographical location, the mineral content of the area and sediment and whether they were derived from hydrogenetic processes, diagenetic processes or a combination of the two 4 Another, less understood method of Mn accumulation has a biogenetic Manganese nodules creation
Textures, Mineralogy and Genesis of Manganese
The manganese nodules from the Blake Plateau consist mainly of microcrystalline to cryptocrystalline todorokite, with minor quartz, clays, carbonates and phillipsite Nodules studied have palagonitic cores, which, themselves, contain segregations of ferromanganese oxides Association of nodules with phillipsite and montmorillonitic clay, regarded as alteration products of palagonite, suggests a genetic relation of nodules to basic submarine volcanismThe origin of manganese nodules on the ocean floor The Al26 content of the TECHNO1 manganese nodule, obtained by a at a depth of 4020 m to the north of the Tuamotu archipelago, was determined The concentration of Al26 in the first section (023 mm) was higher than that found in a Pacific sediment, confirming the postulated concentration of long lived cosmonuclides in manganese nodules for Al26Aluminium26 in a manganese nodule NASA/ADS
Thorium and uranium isotopes in a manganese
In two other sections of the nodule, this ratio is significantly higher, probably reflecting incorporation of diagenetic uranium The upper 25mm section of the Mn nodule shows a relatively smooth exponential decrease in the 230 Th excess concentration (TIMS) The slope of the best fit yields a growth rate of 110mm/Ma up to 245mm depthManganese Nodules, Figure 1 Manganese nodule photographs: (a) crosssection of a manganese nodule from the CCZ showing concentric layering (laminations), fractures, (PDF) Manganese Nodules ResearchGate Polished section of manganese nodule showing concentric laminations around a sandstone nucleus, from DSDP Leg 29, Site 280 (from Margolis, ref 25, p 1087) If we consider the current uniformitarian rates for ocean sediment deposition we find it yields similar conclusionsManganese nodules creation
