The purpose of the data file presented below is twofold: the first purpose is to make available in printed form the basic data relating to the samples collected as part of the... -
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 nodules from the Challenger Expedition
Manganese nodules from Stations 252 and 281 of the Challenger Expedition, collected in 1875, have recently been discovered in the Redpath Museum. The nodules have been found to... -
Analysis of manganese nodules in lakes of Scotland
During the "Challenger" Deep-Sea Exploring Expedition a great many peculiar-looking manganese nodules or concretions were dredged from the floor of the ocean at great depths,... -
On the composition of oceanic and littoral manganese nodules (published onlin...
The following analyses were made some years ago, principally with the object of ascertaining the state of oxidation of the manganese in the nodules. The nodules examined came... -

The Blake Plateau ferromanganese samples were obtained during the USGS GOS74 Expedition in 1965. Most of them are related to a phosphorite substrate. Samples were ground and... -
Chemical analyses of Fe-Mn nodules from the Indian Ocean
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... -
