(Table 2, page 1182) Partial composition of manganese encrustations from Gulf...
Manganese encrustations from two adjacent sampling sites in the Gulf of Aden display markedly different compositional characteristics. The enrichment of manganese, and... -
Chemical composition of oxide-phosphorite pavement from the Blake Plateau und...
Sample preparation technique is critical for valid chemical analyses. A main source of error comes from the fact that the great specific surface area of crusts or nodules... -
Annotated record of the detailed examination of Mn and phosphate deposits fro...
The purpose of the expedition was to test new techniques to determine thickness, distribution and quality of mineral deposits on the Blake Plateau with special reference to... -

Average quantitative spectrographic data are presented for V, Ti, Zr, Ni, Co, Sc, Cr and La in the following Pacific deep-sea cores: siliceous ooze (3), red clay (6), volcanic... -
Chemical composition of a manganese nodule from the Pacific Ocean
By means of spectrographic analysis 96 samples of marine sediments were analyzed quantitatively for V, Ti, Zr, Co, Ni, Sc, Cr, and La, and semi-quantitatively for Ba and Sr. Ca... -

Analysis of Manganese deposits from the Atlantic and Indian oceans
Accumulation rates of 1-2 mm/million years are reported for manganese crusts on deep-sea rocks. These rates are the same as most reported accretion rates for manganese nodules... -
Geochemistry on Manganese nodules from the Indian Ocean
Manganese nodules from a wide range of marine environments have been analysed for a series of elements by optical spectrography, atomic absorption spectrophotometry and mass... -
Description of the Manganese Collection at HIG
The properties of ferromanganese concretions reflect in many ways the marine environment in which they were formed, and points to a variety of probable genetic mechanisms in... -
Analysis of Mn-deposits from the Pacific
The concentrations of rare-earth elements (REE) have been measured in 31 ferromanganese nodules from the Pacific and Indian Oceans and vary by almost a factor of 5. Too few... -

Composition of Pacific sea-floor manganese nodules
This collection of data on manganese nodules on the floor of the Pacific Ocean represents all the information that was available to the authors in May, 1964. It is compiled from... -
Analysis of manganese deposits from the Pacific Ocean
Sea floor dredging by the H.M.S. Challenger, the U.S.S. Albatross, the U.S.S. EPC(R) 857, and vessels of the Scripps Institution of Oceanography shows that extensive deposits of... -
Documentation of manganese nodules form the northwest Indian Ocean
Microscopic and electron probe examination of some manganese nodules show that they consist of segregations of manganese-iron oxides in an interstitial material almost free of... -
