Twenty-one samples of deep-sea ferromanganese nodules collected from the Pacific, Atlantic, and Indian oceans were supplied by the Lamont-Doherty Geological Observatory of...

All the samples were air-dried, crushed, and ground to a fine particle size (<100 mesh). Flame analyses were carried out with a solution that was obtained by the digestion of...

Seven samples of ferromanganese nodules were analyzed using particle-induced X-ray emission technique (PIXE). All the samples were air-dried, crushed, and ground to a fine...

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...

The study reported here involved the analysis of 12 rare earth and 13 minor elements in 13 nodules from the S.W. Pacific; 1 nodule from equatorial N. Pacific (DOMES Site C) as...

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...

Thirty Mn crust samples and associated substrates were taken from dredge hauls collected at 16 sites by the Hawaii Institute of Geophysics. They are located along the Line...

Manganese nodules from the Atlantic and Pacific Oceans were analyzed at Scripps Institution of Oceanography after being ground to < 74 Microns, pressed into pellets, dried at...

The unusual petrological diversity of abyssal lavas erupted along some segments of the Galapagos spreading center is a direct consequence of the propagation (elongation) of...

This report presents megascopic descriptions of deep-sea sediment cores obtained by personnel of the Hawaii Institute of Geophysics on cruises of the R/V Kana Keoki in the...

A detailed geophysical and geological survey of the Mariana Trough, an actively extensional back-arc basin, was conducted in 1976 and 1977 to provide data for selection of...

This report presents megascopic descriptions of deep-sea sediment cores obtained by personnel of the Hawaii Institute of Geophysics on cruises of the R/V Kana Keoki in the...

This report presents megascopic descriptions of deep sea sediment cores obtained by the Hawaii Institute of Geophysics on cruises of the R/V Kana Keoki in the eastern and...

One of the main objectives of the International Phase of Ocean Drilling (IPOD) of the Deep Sea Drilling Project was to determine the geological, geochemical, and geophysical...

40Ar/39Ar incremental heating experiments on three samples dredged from Jingu Seamount indicate that Jingu is 55.4 ± 0.9 m.y. old — older than the Hawaiian-Emperor bend and...

The BLM-OCS (Bureau of Land Management-Outer Continental Shelf) program was designed to establish chemical, biological, and geological baseline on the South Texas Continental...

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...

Data from the Appendix to the PhD Thesis of the author. Supplement to: Gurvich, Evgeny G (1977): Microelements in bottom sediments from the Southeast Pacific. PP Shirshov...
