A selection of manganese nodules and crusts from he Australian marine region have been analysed for their metal content using atomic absorption spectroscopy. From 1983 until...

Manganese nodules and crusts from the Pacific Ocean were analyzed at Scripps Institution of Oceanography using atomic absorption spectrophotometry (AAS). Samples were ground to...

Manganese nodules, coatings and crusts from the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES). Samples were ground...

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...

Sediment samples were obtained from the Scripps Institution of Oceanography. They were subsamples of the powdered material used for studies of the major and minor element...

Oceanic manganese nodules samples were obtained from the Scripps Institution of Oceanography. They were subsamples of the powdered material used for studies of the major and...

Ferromanganese nodules and encrustations have been analysed for selected minor elements (mainly Cd, Cr and Ti) by atomic absorption spectrophotometry. The preparation of...

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...

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...

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,...

Analyses of the total alpha radioactivity distribution in 31 North Pacific manganese nodules yield an average growth rate of 6.8 ( 2) mm /m.y. Samples from a single box core...

he three-site Leg 64 Deep Sea Drilling transect at the tip of the Peninsula of Baja California straddled the transition from continental to oceanic crust. The outer site, 474,...
