Mn nodule samples were decomposed with HCl and fumed with H2S04. SiO2 was estimated by the standard procedure of HF. The residue, after the removal of SiO2, was fused with...

Fifteen manganese nodules from the Australian region have been analysed by the Bureau of Mineral Resources (BMR) from the Department of Minerals and Energy, Australia. These...

Ocean clay samples associated with ferromanganese nodules and crusts have been analysed for their 143Nd/144Nd isotopes ratio. Sr was separated for isotopic analysis using...

Ocean clay samples associated with ferromanganese nodules and crusts have been analysed for their 143Nd/144Nd isotopes ratio. Nd is separated from samples after HF-HNOa...

14 manganese nodules and crusts from sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using Atomic absorption spectrophotometry (AAS) From 1983...

142 manganese nodules and crusts from sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES). From 1983 until...

16 manganese nodules and crusts from 11 sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using atomic absorption spectrophotometry (AAS). Samples...

23 manganese nodules and crusts from 17 sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES). Samples were...

In 1969, Kennecott Exploration Inc (KEI) was formed and between 1970 and 1974 KEI conducted seven exploration campaigns for manganese deposits. With progressively more detailed...

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...

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...

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...

ur continuous photographic transects (45 to 90 km in extent) were made with deep-towed, wide-angle cameras over the manganese pavement region of the Blake Pla¬teau. The photos...

A seabed nuclear probe which was designed to measure up to 30 elements at parts per thousand to parts per hundred levels has been tested for the analysis of simulated manganese...

Sediments dredged from the flat top of Capricorn Seamount on the eastern edge of the Tonga Trench show it to be of probable Miocene Age. Tonga Trench is judged to be early or...

Cosmogenic beryllium-10 activities have been measured in marine accumulations of up to about 6 m.y age by conventional beta counting technique and by accelerator mass...

This report presents megascopic descriptions of deep-sea sediment cores obtained by personnel of the Hawaii Institute of Geophysics on cruises of the R/V Kana Keoki in the...

This report presents megascopic descriptions of deep sea sediment cores obtained by the Hawaii Institute of Geophysics on cruises of the R/V Kana Keoki in the eastern and...

This report presents barrel descriptions of deep-sea sediment cores obtained by the Hawaii Institute of Geophysics on cruises of the R/V Mahi during 1970 in the western Pacific...
