Mercury contents of selected marine manganese nodules
Manganese nodules were selected from various areas of the Pacific, Indian and Atlantic ocean. They were analysed using a mercury vapour discharge technique. The minimum... -
Chemistry of manganese deposits from the Hawaiian Archipelago
Selected manganese deposits from the Hawaiian Archipelago were submitted to chemical analysis using two methods. Atomic absorption spectrophotometry was used for the analysis of... -
Chemical composition of the internal layers of manganese deposits from the So...
The chemical composition of layered deposit inside zones has been determined for ferromanganese nodules and crusts retrieved in the South Pacific Ocean during various R/V... -
Thorium isotopes measurements inside internal layers of manganese deposits fr...
The ratio of 230 Thorium excess over 232 Thorium isotopes has been determined for different layered deposit zones inside ferromanganese nodules and crusts retrieved in the South... -
Chemical analysis of of manganese nodules and crusts from the Pacific Ocean a...
Ferromanganese deposits from the North Pacific and Blake Plateau have been sampled from potential mining sites either by the industry (Deepsea Ventures, Kennecott Corporation,... -
Elemental composition of ferromanganese crusts from the Hawaiian Archipelago
The paper presents the results of studies of ferromanganese deposits in the Hawaiian Archipelago. The chemical composition of ferromanganese oxide crusts and their associated... -
Chemical composition of ferromanganese crusts dredged from the Marshall Islands
In 1984, the U.S. Geological Survey (USGS) conducted a reconnaissance cruise L9-84-CP aboard the R/V S.P. LEE along the northern Ratak Ridge, Marshall Islands and retrieved... -
Chemical analyses of manganese nodules and crusts from the Indian, Atlantic a...
Ferromanganese nodules and encrustations have been analysed for Mn, Fe, Co, Ni, Cu, Zn, Pb, Ca and Al by atomic absorption spectrophotometry. The preparation of... -
Atomic absorption spectrophotometric determination of selected elements in fe...
Twenty-one samples of deep-sea ferromanganese nodules collected from the Pacific, Atlantic, and Indian oceans were supplied by the Lamont-Doherty Geological Observatory of... -
Analysis of deep-sea ferromanganese nodules using flame atomic absorption and...
All the samples were air-dried, crushed, and ground to a fine particle size (<100 mesh). Flame analyses were carried out with a solution that was obtained by the digestion of... -
Analysis of deep-sea ferromanganese nodules using particle-induced X-ray emis...
Seven samples of ferromanganese nodules were analyzed using particle-induced X-ray emission technique (PIXE). All the samples were air-dried, crushed, and ground to a fine... -
Neodymium isotope ratios for iron-manganese crusts and manganese nodules of t...
Iron-manganese crusts were chosen from existing collections in order to cover as wide an area and depth range as possible. Sampling was concentrated in the Central Pacific... -
Rare-earth and minor elements concentration in manganese nodules and crusts f...
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... -

Connectivity is a fundamental process driving the persistence of marine populations and their adaptation potential in response to environmental change. In this study, we... -
Observation of ferromanganese crusts on lava deposits recovered near the Gala...
The unusual petrological diversity of abyssal lavas erupted along some segments of the Galapagos spreading center is a direct consequence of the propagation (elongation) of... -
(Table 1, page 67) Chemical analyses and XRD determined mineralogy of mangane...
The uptake of Ni and Co in the hydrous Mn oxide or the amorphous Fe-oxide phases of ferromanganese deposits in the oceans was studied by electron-microprobe analyses of 17... -
Annotated record of the detailed examination of manganese nodules from around...
Manganese nodules collected off Baja California have layers (zones) which are texturally and compositionally distinct. Massive and mottled zones consist mostly of... -
Major elements geochemistry of manganese nodules from the Pacific Ocean
Analyses of the bulk oxidation state of marine manganese nodules indicates that more than 98% of the Mn in deep ocean nodules is present as Mn(IV). The samples were collected... -
Annotated record of the detailed examination of Mn deposits from the Mariana ...
A detailed geophysical and geological survey of the Mariana Trough, an actively extensional back-arc basin, was conducted in 1976 and 1977 to provide data for selection of... -
