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...

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...

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...

This paper, explores the possibility of using manganese nodules for studying the rates of authigenic removal of trace elements to the ocean floor, i.e. considering only trace...

Using X-ray fluorescence spectrometry major and trace elements have been estimated over a larhe variety of manganese nodules and crusts from th Pacific and the Indian Ocean. Of...

A compilation of chemical analyses of Pacific Ocean nodules using an x-ray fluorescence technique. The equipment used was a General Electric XRD-5 with a tungsten tube. Lithium...

Using spectrochemical techniques Fe, Si, Mg, Co, Ni, Cu, V, Mo, Ti and Tl have been estimated in nineteen manganese nodules, eight from the Atlantic ocean, seven from the...

In an earlier paper by two of the authors the conclusion was reached that the 33 recognized species of oxides of Mn could be separated into 3 groups: 1) those which appeared to...

Concentration (ppm) of some chemical elements in coastal sediments obtained along core MD-3, representing marine (e.g. Br, Ca, Cl, and Sr) and terrestrial (e.g. Fe, Ti, and Mn)...
