Inside core 710KH, manganese micronodules are much more abundant in the coarse fraction (> 40 μm) of the dark brown clay horizon than in the upper sedimentary unit and are...

The chemical composition of sediments at various levels inside core 710KH also show a clear distinction between the overlying calcareous, siliceous-bearing to siliceous-rich...

Ferromanganese nodules were retrieved at different levels inside a core taken in the vicinity of the Hawaiian Islands. Total iron contents were determined by the bichromate...

Manganese nodules and crust were retrieved during the KH-68-3 campaign of the R/V Hakuho-Maru. Their chemical composition was determined by a combination of methods: traditional...

Manganese nodules were retrieved during the SO06 (R/V Sonne) and COPANO (R/V Le Suroit) campaigns as part of the international "Hawaii-Tahiti Transect Program" initiated at the...

Several microprobe chemical analysis on an ellipsoidal Mn nodule with rough surface (5.4x4.8x3.8 cm) and a volcanic core. Measurements were performed on a cross section. From...

Manganese nodules and sediment samples were collected in the Central and South-West Pacific ocean during R/V Sonne campaign SO06 as part of the I.C.I.M.E. (International...

The authors have selected for analysis a manganese nodule from Station 20 of the PLEIADES Mn7601 campaign. This "apple" shaped nodule (6.5x3.0 cm) was laying on a bed of...

Using radiochemical methods, the authors have measured the distribution of uranium, thorium, radium, polonium and protactinium isotopes from the top and bottom sides of the a...

For evaluating the efficiency of high-temperature sulfation as a potential technique used in the extraction of metals from manganese nodules, the authors have chemically...

A geochemical (major and trace elements including rare earths) study was made of core samples drilled between the Touamotou Archipelago and the Marqueses Islands during the...

Manganese nodules were retrieved from the Pacific Ocean during the CNEXO-NIXO campaign and the GH76 and GH80 campaigns of the R/V Hakurei-Maru. Their chemical composition was...

During the campaign SO23/2 (R/V Sonne) in the South China sea various manganese deposits were retrieved by dredging. Two representative samples were selected for chemical...

Four hundred and twenty kilograms of manganese nodules were recovered at Station U205 in the Tasman Sea. They were sorted by size class. Representative subsets for each size...

The table presents the REE contents and fluxes of manganese nodules and crusts from the Manganese Nodule Program (MANOP) site H (6.5° N, 93° W) in the eastern equatorial...

Selected manganese nodules from the DEEPSONDE and BENTHIFACE expeditions conducted by the Scripps Institution of Oceanography (SIO) in the northeastern equatorial Pacific have...

Manganese nodules from expeditions conducted by the Scripps Institution of Oceanography (SIO) in the Clarion-Clipperton Fracture Zone (CCZ) in the Pacific Ocean have been...

Manganese nodules were retrieved during various cruises of the R/V Vema and R/V Robert Conrad from Lamont Doherty Earth Observatory (LDEO). Their chemical composition was...
