Annotated record of the detailed examination of Mn deposits
Beginning in 1983 the USGS searched major oceanographic institution dredge archives for samples and data relevant to the USGS Woods-Hole Ferromanganese Crust Data Base. With the... -
Ferromanganese crusts and nodules chemical analyses from the USGS Reston anal...
Based on comparative studies on the utility of ICP, atomic absorption, and other techniques for the elemental analysis of geological samples the authors decided to pursue a... -
Neodymium isotope data for manganese nodules, crusts and sediments
Ocean clay samples associated with ferromanganese nodules and crusts have been analysed for their 143Nd/144Nd isotopes ratio. Nd is separated from samples after HF-HNOa... -
