The study reported here involved the analysis of 12 rare earth and 13 minor elements in 13 nodules from the S.W. Pacific; 1 nodule from equatorial N. Pacific (DOMES Site C) as...

72 surface sediments associated with manganese nodules from 31 sites in the Central Pacific Ocean were obtained during CCOP/SOPAC cruises in 1980, and from the core collections...

61 manganese nodules from 31 sites in the Central Pacific Ocean were obtained during CCOP/SOPAC cruises in 1980, and from the core collections at the University of Hawaii,...

Thirty Mn crust samples and associated substrates were taken from dredge hauls collected at 16 sites by the Hawaii Institute of Geophysics. They are located along the Line...

Chemical elements in the samples analysed were determined by atomic absorption spectrophotometry after completely dissolving the samples in a mixture of hydrofluoric, nitric and...

The Marine Minerals Database contains geochemical analyses and auxiliary information on present-day marine deposits of primarily ferromanganese nodules and crusts. Some data for...

The geological characteristics and Fe-Mn deposits from the North wall of the Romanche trench (Atlantic ocean) were studied in order to investigate possible relationships of...

The structure of the principal manganese minerals of the nodules, todorokite and birnes- site, is determined by the structure of hydrated manganese dioxide. Using this fact and...

An extensive field of iron-rich, nickel- and copper-poor manganese nodules covers the deep sea-floor of the northeastern quadrant of the Southwestern Pacific Basin, and the...

The shale-normalized REE patterns of manganese nodules from the northwest Atlantic show enrichment in Sm and Eu relative to the heavier and lighter REE, excluding Ce, and are...

We discuss the differences in chemical composition between the two opposite sides of a deep-sea manganese nodule. The upper side, facing sea water, contains a hydrogeneous...

The nodules examined were sampled during the R/V Valdivia cruises VA 04, 05, 09, 13/1, and 18. The majority of these samples was taken from a region extending from 135°w to...

Manganese nodules retrieved by early cruises of the R/V Hakuho Maru in the Pacific Ocean and the R/V Umikata Maru in the Indian Ocean have been chemically analysed for their...

Manganese nodules retrieved by early cruises of the R/V Hakuho Maru in the Pacific Ocean and the R/V Umikata Maru in the Indian Ocean have been chemically analysed. Samples were...

Of the 26 samples collected during VA-05/1 cruise of R V Valdivia during 1972, 19 were nodules of different forms, 4 ferromanganese crusts and 3 cylindral nodules. Nodules and...

Selected manganese nodules both from deep-sea environments of the Pacific Ocean and epicontinental near-shore areas (Canada west coast and Baltic Sea) have been studied to...

Surface as well as buried manganese nodules are found in core SO11_710KH. Buried manganese nodules are found at two horizons within the sediment column. These nodules show...

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...

Scoriaceous Mn crust fragments on travertine-like nontronite deposit were retrieved near two hydrothermal vents while surveying the rift valley of the Mid-Atlantic Ridge using...
