Accumation rates of manganese in manganese nodules using total alpha activity
The manganese content of 4 manganese nodules was determined by atomic absorption. The decrease of total alpha activity was used to evaluate Mn accumulation. Because CaCO3 is a... -
Ferromanganese nodules and crusts chemical analyses from SIO outside of the I...
The data encoded in the Scripps Institute of Oceanography Nodule Data Bank (SNDB) was used as a model for the publication of USGS Ferromanganese Crusts Data Bank. The chemical... -
Rare-earth element analyses for iron-manganese crusts of the Pacific Ocean
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... -
Chemical composition of Pacific, Indian and Atlantic ocean manganese nodules ...
Manganese nodules, coatings and crusts from the Pacific and the Indian oceans were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES).... -
Chemical composition of ferromanganese nodules from the Pacific Ocean using X...
Manganese nodules were retrieved during cruises of the Scripps Oceanographic Institution (SIO). Their chemical composition was determined using X-ray fluorescence. From 1983... -
Lead isotope ratios for manganese nodules
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... -
Chemical analyses of manganese nodules from the the Pacific Ocean determined ...
A variety of manganese nodules from the Pacific Ocean were selected from dredge performed during various ship cruises of the Scripps Institution of Oceanography (SIO. For Mn and... -

Chemical composition of marine manganese nodules from two potential mining si...
Manganese nodules were selected from various potential mining sites of the Pacific ocean. They were dried by heating at 110°C for 24 hours and ground to powder before their... -
Chemical composition of marine manganese nodules from four potential mining s...
Manganese nodules were selected from various potential mining sites of the Pacific ocean. They were dried by heating at 110°C for 24 hours and ground to powder before their... -
Tellurium analyses of 12 samples of manganese oxide nodules from the Pacific ...
As a part of a continuing study of the distribution and abundance of tellurium in various materials of the earth's crust, analyses were made of 12 samples of manganese nodules... -
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... -
Chemical composition of Pacific manganese nodules and crusts analyzed at Scri...
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...
