Radiochemical analyses have been performed on micro-samples extracted from various surface and inside layers of a buried manganese nodule recovered from core CH71-09 at a depth...

The authors have measured element and isotope compositions of He and Ar gases in 10 nodules dredged from Mariana Trough (opening back-arc basin) and the Ogasawara region on the...

The authors have selected manganese nodules broadly representative of world oceanic areas. Approximately 1 gram of each manganese nodules was leached with 25-mi 6N HC1. Lead was...

During the campaign SO23/2 (R/V Sonne) in the South China sea various manganese deposits were retrieved by dredging. Two representative samples were selected for chemical...

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...

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...

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...

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...

Samples were collected in the South Tasman Sea basin during the Cruise 36 the USNS Eltanin, Cruise 36. The manganese oxide deposit, either manganese crust on manganese nodule...

9 manganese nodules from sites in the Central Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray fluorescence analysis. From 1983 until 1989...

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...

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...

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...

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...
